Hello,
Recently found this four bladed propeller piece probably a crash relic.
markings
J.W. Walker & sons London
150hp Sunbeam AD502
on the front ADP in a circle on each blade and the number of the blade 1,2,3,4
6 bolt holes
there was a clock inside so I don’t know the axle diameter

There isn't a lot to go on but I found some info by Googling Sunbeam 150hp aero engine.

Hello,
thanks for the help.
it’s probably according to the Ad502 number for a coastal airship RNAS 1916
greetings

I thought maybe a seaplane but the one I thought it was, had a two blade propeller so that could make sense.
Interesting, it's a shame it's been butchered.
