Okay okay... I give up! I found it in a thrift store. Trebor- same for you or anyone- I'll give you 10% if you can find someone to buy it for 100k. Heck, I'd do it if you found someone to buy it for 50k!
Hi,
These blades were used on the Bell P-63A-10 aircraft, 11'-0" diameter, in the A642S-D3 hub.
They may also have been used in earlier blocks of the P-63A.
