A pal of mine has sent me these images of an Armstrong Whitworth propellor boss!
Any ideas on the " what, where, when" of this substantial piece of timber would be greatly appreciated!

Yep. A couple of details more for the prop ....

DRG. LP. 2390A - also DWG, the drawing number, referring to the blueprint from which the propeller was manufactured.
160.HP. BEARDMORE - the engine type
ARMSTRONG WHITWORTH - the manufacturer
G1013 N13. - possible the prop serial.

D. 2840 (2-840) - the number, referring to diameter/length of propeller in inches, meters, cm, mm ... etc
P.1900 - the pitch of the propeller
G1013 N13. - see above.
