So what was on the plate on the reduction gear case in the second photo? Or was that where (on the left) that the data serial plate should have been but was absent?

That where I would have thought it would be but there is no evidence of one being attached and only references to the case material and inspectors stamps.

It's probably a case of working out whether it's IX, or X, ie was it on an Anson or an Oxford. It's unlikely to be a V as the Avro 626 had, not sure about the difference between that and the other two.

Given the number of Oxfords scrapped at Blenhiem (and the fact that the Ansons were re-engined with Mk Xs)you can be 98% sure its a Mk X.

We were wondering if there were any notable differences that would have given us a clue. I am looking forward to th arrival of the containers and the cowl panels for the engine. |

RNZAF Ansons were NEVER re-engined with Cheetah Xs - however in 1943 or 1944, the Ansons were retrofitted with Oxford cowling rings in place of the original "helmeted" cowls which had been found to provide insufficient cooling in summertime NZ, leading to failure of valves and/or valve springs, etc. So far as I know (from reading their general descriptions somewhere - perhaps Jane's AWA?), there were quite a few differences between Cheetah IX's and X's, but most were seemingly concerned with the arrangement of accessories on the rear cover.

Mike
I have been told by an Oxford expert that you have a Cheetah X there.
Jason.

The Cheetah V was not supercharged, whereas the IX and X had geared fan for mixture distribution and was considered medium-supercharged.
The differences between the IX and X seem to be that the X had provision for electric and hand starting, as well as provision for hydraulically operated accessories including a variable pitch prop. The X weighs more as a result, but if you are missing bits that might not help you at all.

Thanks for the info guys - we really appreciate your input and support. If you are ever over our way on a Wednesday or Friday come down to hangar 3 and say hello.
Thanks too Jason for your input - we will call it a Cheetah X until proved otherwise. How is your project coming on. I understand that the containers are not that far away with all the bits from Blenheim.

When we arrived back at Tauranga on Thursday afternoon these four boxes were unloaded and lined up against the hangar. Four De Havilland Goblin engines still in there crates. I had a peek into one of the boxes and the engines was wrapped in plastic sheet. Not sure whether they are new or overhauled engines.  IMG_6520 by Mike Feisst, on Flickr |

I understand that the containers are not that far away with all the bits from Blenheim. I've made a start Mike, not much to show at the moment. Concentrating on cleaning up/painting the nose leg and wheel ready for fitting to the pod and thinking of configurations for the rear support frame. |

They wouldn't be new Goblins, at the end of the Vampires service they were so short of bits, especially impellers and turbines, that engines were recalled from ATC units to see if there were parts that could be overhauled. Likewise the scrap dump at Woodbourne was raided for the same reason.

they could be new, maybe the Storemen took there job too seriously and forgot they also had to be suppliers?  |

I had to pick something up from the museum today and I see that the 2 40' containers from Blenheim have arrived and are parked across from hangar 3.

We spent the day unpacking the two containers from Blenheim. One complete Vampire NZ5751 plus about another ten Goblin engines and other assorted parts. In amongst these were some cowl rings and panels for the Cheetah when attached to an Airspeed Oxford. Will be interesting to see what we can achieve with these parts. The Vampire looks to be complete and there appears to be very little missing from the cockpit - just some broken instrument glasses. Andrew had to check out the cockpit of our latest acquisition for size. One of our volunteers, Ken Brooking, was helping and he stood gazing into the cockpit and telling us the function of all the levers, instruments etc in there and some of the stories associated with his time in the aircraft. He reckoned that it was so easy to fly that anyone could do so.
