View Full Version : Unidentified propellor tip

11-04-2010, 06:25 PM
Hi All
I recently picked up, in a deal, a propellor tip that came from the effects of a WW1 RFC/RAF Observer, he used another tip of the same type as a photograph frame.
My propellor tip has a marking on it which i'm assuming is a manufacturers mark, it is-

A.I.D 75

Could anybody idenify the maker, and give me an idea on what aircraft it may have been used on.
Any information would be much appreciated.

Good Morning Graham and welcome to the forum,

AID indicates the British airworthiness organisation in WW1, the Aeronautical Inspection Department. I have seen the stamp of inspector number 75 on two Bristol props, for the Bristol Scout C and the Sopwith Pup (for whom Bristol made props). Some of these inspectors moved around, although I have no evidence that No 75 did, but a small element of doubt remains.

With kind regards,
