Comments: Sopwith Pup propeller for Gnome engine. The "P" in the drawing number on this indicates that it was made by the British and Colonial (Bristol) factory.  The "D" indicates the diameter of 2.550 meters, and the "P" below that indicates a pitch of 2.610 meters.  The engine is a 100 HP Gnome Monosoupape.  Many propellers have a "G" and an "N" sequence, but I have not yet found what that may indicate.  The "5885" is most likely a simple production serial number.
