'Evening John,

The hub data you have given us do not relate to the prop shown in the link, which is an SE5A propeller.

Your data translate as:

AB8218 a late 1918 Air Board drawing number for a Bristol F2b, commonly called a Bristol Fighter, sometimes reduced further to a Brisfit.

D2940 Prop diameter in mm

P2580 Pitch also in mm

Sunbeam Arab 1 The engine used in a few Brisfits

F2B The aircraft.

I am unsure which of these two sets of data are on the prop which you bought.

With kind regards,
