Looks English in the first two pics, but after seeing the last few I'm thinking Russian - Il-2 or MiG 3 maybe?
There are no Cyrillic letters on that prop. You're looking at upside down inspection stamps. I believe that's a Rotol Propeller but I have to do some more research. Additionally Propellers aren't always designed around one airframe. Depending on the hub/ blade combo, they may fit on several different aircraft.
From what I can see it looks like a Hamilton Std. prop., possibly made by de Havilland. I'm still researching.
You are more likely right than wrong. What has me confused is photo 6. The Star Punch has No5 which appears to be english for "Number 5" on the bottom and a cyrillic V (B) and P (upside down U). The B could certainly be a Roman letter B but the upside-down U is a very strange character for an english language stamp.
Can't see a Rotol logo anywhere, but I agree that it has the look of a Hamilton Standard type of prop. The form and shape of the numbers stamped into the surface or on plates does not look British though - the shapes are more 'Continental' in style. First impressions are German or Russian made.
Looking forward to your findings Joe, as I still feel it could be Russian. They recovered an La-5 here in Hungary which had very similar markings.
