Hi and welcome to our forum.

Your hub is British and from an airship used by the Royal Navy in WW1.

Your data decodes as;

Sage no 407a made by the Sage Co. in Peterborough, England
A.D.502 LH AD indicates the Aviation Department of the Admiralty, 502 the drg no, and LH the rotation of the engine.
D 3050 diameter in mm
P 1930 pitch in mm
70 sunra n probably this reads 170hp Sunbeam Crusader, the engine used

The airship was called the Coastal Airship and your prop comes from the forward engine.

With kind regards,

Bob
