Help with wooden prop

[jpw]

My sister has a wooden prop we would like to get more info on.
It has the following markings on it:
DRG No LP 3640 RH - I've found that this means Lang Propeller with a right hand spin.
150 HP BRI - I've found that this is a Bentley BRI engine.
P2508 or 2500 - pitch
D2635 - diameter
G1393 No46 - ???
2658 tractor - ???
AD456 - presumably air department?

She believes it came off a Sopwith Camel and I'm trying to find out how to find out which aeroplane it came off. Any ideas ???
Thanks,
JPW

She's correct. It was used on the Sopwith F1 and 2F1 Camel. You will almost certainly never find a specific airplane that it was used for, however, if in fact it was even actually mounted on one.
