Life has gone on through the degrees of Levels but apart from the further units as per the last post a windfall of Hudson stuff came our way.
One item was one of the adaptor racks (go back to page 6 or 7 here about mounting bomb racks in the bomb bay) and so the chance has come about to add another unit to the bomb bay.
The unit has been stripped, primed and painted (the green thing top of shot) and one of today's missions was the fabrication of the stay from it to the actual bomb rail (the bare metal item obvious from the rear of the adaptor to the rail near the black sway stay...three more to go!
Now we just need more of those adaptor units!

Enough of this stuff from the far workshop, time for an update from Mossie world. The big fuselage repair continues to take up time without generating visual progress, so we'll leave that for now. In the meantime I have been slowly chipping away at the rear fuselage. Here are a few before and after shots: Looking forward from the rear fuselage hatch:
What it looks like now: A. Bracket for A.1275 beam approach amplifier. Still hunting for one of these. B. Telephone/Mic cables for the TR1143 VHF radio C. and D. Mounts for the TR1143 VHF radio crate. We have the radio but need the crate E. Rudder trim cables. F. Cover for Graviner crash switch and red downward ID lamp. G. Elevator differential and rudder layshaft:
A. Brackets for pneumatic reservoirs. One of these is now installed but of course I forgot to photograph it. B. Compartment lamp C. Bracket for aneroid switch controlling the engine superchargers. We are still after the actual switch. D. Location of the pneumatic and hydraulic panel. We have gradually been acquiring components for this panel, we'll probably have to manufacture the panel itself. E. Insulator for TR1143 VHF radio aerial element
Pneumatic reservoirs waiting to be installed. Note stencil, which George has painstakingly hand cut based upon the original. Most of the stencils we have found inside the aircraft were originally hand-cut according to RNZAF Museum expert Barf:
Looking aft from the fuselage hatch before:
...and now. A. Water drain trap on pitot presure line. B. Insulator for TR1143 VHF radio aerial earth element. C. Cables for R.3078 (top) and R.3121 (bottom) IFF aerials. The aerials for the earlier R.3078 were mounted in the tailplanes with separate aerial leads running either side of the fuselage, this was superseded by the R.3121 with a single type 90/93 blade aerial mounted in the top of the fuselage aft of bulkhead 5. We are still looking for one of these aerials. D. Bracket and connector for the TR1143 VHF radio. The aerial elements run forward, aft and downward from this bracket. E. Pressure venting lines. The pressure venting system uses air from the pressure side of the engine-driven vaccum pumps to pressurise the drop tanks and fuselage fuel tanks. Excess pressure is vented through the bottom of the fuselage via these pipes. F. Openings for green and amber downward ID lamps.
Looking forward towards the aft hatch: A. ARI. 5083 "Gee" Aerial loading unit. B. Opening for F24 camera C. Flow control valve for tailwheel retraction hydraulics D. Pulley(s) for rudder cables. We are still short one pulley/bracket set. E. Elevator trim cables - currently coiled up at this bulkhead. F. Rudder trim cables G. Insulator for TR1143 VHF radio aerial element. H. Mount for the beam approach aerial. Still hunting for one of these. J. Cables for R.3078 (top) and R.3121 (bottom) IFF aerials.
Elsewhere the instrument panel wiring is complete and the panels are now stored pending reinstallation. The last parts we were missing from the port instrument panel was the radiator temp gauges. These were obtained thanks to this forum a few months back. The remaining holes are for boost, oil temp and oil pressure gauges which we have but which will go in when the panel is installed:
We recently obtained a (super rare) Mk VIIIC Oxygen regulator to complete the lower centre instrument panel. The wartime Mossie had separate regulators for the pilot (in this panel) and the nav (in the floor beside the nav's seat). Post war they were modified to a single regulator of the later pattern on this panel. We are still afer a second regulator if anyone has one laying around:
George has been working on restoring the two firewalls. Here is a couple of shots of what he started with:
The long thin rectangular doodad in the centre of this shot is the Graviner flame switch. The wartime (and RNZAF) Mossie had two each side, this was later modified to 6(!) per side. The ladder-like bracket on the right is the bracket for the Graviner fire extinguisher bottle, and the meaty electrical connector is for the starter motor (I'm looking for a couple of the socket to match this). Note the damage at top right of the shot (the firewall is upside down in these photos).
Here's what it looks like now. It has been almost entirely de-rivetted, had extensive repairs and painting, as well as fabrcation of new seals around all the openings and the perimeter.
Finally a nice little curiosity. Here is the panel for the bay under the 4 .303 Browning Machine Guns. Held on by 5 Dzus fasteners - note the red alignment marks. We're fairly sure this came off NZ2328 (TE758).
This is the inside of that panel:
We're fairly sure the panel originally belonged to HJ896, which according to this link had a career ending whoops at High Ercall on 12/1/1944, and presumably was reduced to produce and the panel recycled into TE758, which was built in 1945.
I hope this is of interest, please continue to support us if you can, via Givealittle, by buying a book, or with donations of bits or materials.

Just to keep the pressure on the wooden team best post something from the other side ...
This week has been small stuff following on from last post on the bomb rack. But here for a comparison if one of the US racks that replaced the AirMin ones.
Obviously when the RNZAF went up Pacific they would have drawn ordinance from US sources and so the Hudsons had to use US bomb racks in lieu of AirMin as the RAF bombs had just one lifting lug (see just one hook in the AirMin rack) while the US had two so here's the US rack that came with one of the adaptor units we have received over time.

Originally the RNZAF shipped up its own supplies of RAF bombs (mostly 250 lb GPs) from New Zealand stocks, but this became a bit of a pain, supply wise, so aircraft in the forward area eventually went over to American racks (or "carriers") to simplify things. The later American aircraft supplied to NZ were of course already equipped with American racks (TBFs, SBDs, PV-1s, PBYs, F4Us, etc), but these acquired a rather unenviable reputation for general unreliability in service. However the advantages of accessing American-supplied bombs in theatre meant that the American racks were retained and they learned to live with them. By 1945 they seem to have improved the standard American racks to be somewhat more reliable. Armament Officers in the theatre ceased to moan about them so much in their correspondence. David D
Somewhere I have a couple of photos of the bomb rack we used to mount a dummy bomb in the Avenger at Wigram. mainly to help keep the tail down during engine runs as with no winch installed it was noted that she was getting light on the tailwheel, even with the stick hard back. But also to demonstrate the use for the bomb-bay We didn't do full power runs but kept to about 1800 RPM. The rack had a solenoid with an electrical plug attached which didn't line up with anything in the Avenger's bomb-bay so possibly not the correct one apart from the dimensions for mounting it.
The Auster should be recognised for what it is: a gentleman's aerial touring carriage and a nice aeroplane.

More Hudson news this week......
For a long time I've been pondering four mounting brackets that are on the rear face of the front shear beam of the wing where it comes through the fuselage and forms the boundary between the radio ops bay and the pilots' cockpit...what was mounted there was the question and of course seeing it was the radio bay what radio kit was the question. None of the Hudsons in NZ or AUS that I have had access to gave an answer, nor the manuals.
A few weeks ago we got a drop of materials and in it were a number of items painted in the characteristic Lockheed-Hudson green one of which was an equipment box of 6 relays. Studying it I looked at the rear face with four brackets on it with Lord shock mounts and the bell rang and light came on and so I offered it up to those long considered mounts and got a match.
As relays like this aren't part of the radio fit then the manuals revealed them to be part of the the controls for the oil cooler exit flap. There are two pairs of three relays, port and starboard, and in each of those a pair are for open and close of the flap and one for "dynamic brake", something still to be resolved.
However the Lord mounts were beyond redemption but easily replaced and so today the unit took its place.
It came complete with cable fitted but cut off and so now the question is where it ran to, best guess so far is to the major junction box which runs alongside the pilot above and slightly left of the top of the shear beam as you see in he first photo above....just another Hudson conumdrum!
apologies for the image quality in the workshop on a dull cold day

If you go back to page 12 and the installation of the upper accessory box on the Goblin, we, to quote the current vernacular, reached out to various associates to try and locate the corresponding lower item we also needed and one came up with a unit which had had a somewhat hard life out in the elements. This was very kindly transported to us by a resident of Heathcote Valley on a personal trip around the island on family business.
So we processed it through the usual strip, clean, prime and paint routine and the patient responded to the treatment admirably.
This week's work saw it appended to the Goblin and then the first accessory, the Lockheed hydraulic pump, which had followed it through the refurb workshop, took up residence.
Next week's object is the starter motor which horizontally opposes the hyd pump.
We're in the market for the sump, which is the bottom-most case here, as other items hang off it....so as usual any one out there can help???

Well have to say sorry but got distracted from the Goblin starter this week due to lousy weather so reverted to another project easier to deal with at home.
We need to go back a tad in time to when we installed the radio fit through the Hudson but in the navigator/bombaimer we were missing one junction box so we used one we had available, perhaps even ex Harvard as shown here, the grey fellow in the centre of the three.
It was/is however too wide in plan and too thin in profile but had to do for the meantime.
In the last few weeks, amongst the recent bits acquired, including the relay box reported the other week,we got a rather bruised and battered junction box which turned out to be the real McCoy.
So after it has been straightened out and the interior dealt to it took over position today.
Now we have to cable it in.
When we installed the substitute we followed how other local restorations had dealt to this and so used a shielded cable from the box to the Bendix 3250 operator's unit. However this week when delving in the Erection and Repair manual we found a photo which shows the cable to have been a laced group of wires which tallied with the fact that newly acquired box had a rubber grommet in the top, and so Brother Angus, he of Mosquito wiring fame, is making up the required piece this week.
We also had to make a lid for the box but now made that can't go on until the cable ends terminate on the racks so installed.
So for now here things stand!
So a week of one step back but a big step forword.
