Any ideas what these propeller blades came from?

[jaybee]

I have acquired 2 cut down propeller blades and am keen to try and find out what aircraft they came from.

The blades have no marking but are wooden, almost certainly ex-RNZAF (came from a gentleman who was in the RNZAF during WW2) and known to date from WW2 or just after.

Blade 1 is roughly 1220mm long, 250mm at its widest and 80mm thick at the end. My guess is something like a Hawker Hind.


Blade 2 is roughly 850mm long, 245mm at its widest and 50mm thick at the end. The pitch is finer than on blade 1.


All suggestions would be most welcome!

Thanks

Off trade Me , dam you were the one who swooped in before me.

Ahaa, another forumite on TM!

Cleaned up they will look great. Good luck with the history

[patmurphy]

Any part numbers on them? That might help narrow the maufacturer and type down.

[scrooge]

Probably not, any numbers would be on the hub or blade root, which aren't there.

[jaybee]

Thanks for interest but no numbers present unfortunately.

Blade 1 matches the rough shape and profile for those found on pictures of Hinds...........

Blade 2 looks subtly different having matched both starting at the tip.

A wild shot in the dark here: Not off the Seafire that was left behind and ended up at Hobsonville?

Now that would be fantastic! My understanding is that the orginal owner was demobbed at war end, but I am double checking to see if there is any possible connection. Thanks for the suggestion.

I have been double checking the blades against each other and now suspect that they may 2 parts of the same prop; depending on which angle you look from, they are very similiar.

The bigger blade has cleaned up well



And yet another propeller that needs ID'ing. This one is some 1770mm long, is laminate, and has 8 bolt holes in the hub (underneath the barometer). There are no numbers or markings. The story is that it was won as a 'war bond' type raffle prize in Hastings during WW2 and remained with the owners until I acquired it. Suggestions?

Possibly Oxford prop for that last image?

[suthg]

The last "barometer prop" certainly looks like the Oxford Cheetah prop seen below...

Certainly looks like the right shape and hereditary.

And the original pair of props look a bit like this one - with the odd pointed tip...



But whether it is logical from a Walrus...

This propeller is a Right Hand pusher prop used on Walrus aircraft. The Pegasus VI engine was only used in Walrus aircraft in New Zealand

[shorty]

The Walrus was fitted with a Pegasus IIM2 engine. Vildies had a IIM3

[davidd]

Later Walruses indeed had the Pegasus VI engines, I have seen such a prop at Wigram with these markings stamped thereon - these props were actually two separate 2-bladers bolted on together to form a squat four blader. Very early Walruses had the IIM-2, but probably 97% of the type were delivered from new with the Pegasus VI fitted. However the IIM-2 Pegasus (as fitted in early Baffins) was not interchangeable with those fitted in the Walrus, as the thrust bearings on the crankshaft would have been facing the wrong way, one for a pusher the other for a tractor prop! Probably other diferences too. I think the only NZ Walruses fitted with the earlier Pegasus were K5774 and K5783.

Correction to my previous post! From AP 1451C, Vol 1, 3rd Edition March 1937.
The Pegasus IIM-2 Was NOT fitted to early Baffins - these had IM-3 engines, later ones had IIM-3 (as for most Vildebeest and Vincent, etc.) The IIM-2 was built purely as a pusher installation, with a different reduction gear ratio (0.666:1); the IIM-3, usually fitted with the longer, 2-bladed props, had ratio of 0.5:1 reduction. Other major differences between the -2 and -3 variants was that all the intakes, cooling baffles, etc, had to be drastically modified to face the correct way with reference to the prevailing airflow. Should have consulted the AP earlier, but did not have handy access until a couple of days ago.
