I'm looking for information about an old prop

160ps siemens d280 st430 axial edulzug

I only find the siemens halske SL III engine with 160PS.

are there any other siemens engines with 160ps?
which planes used a prop diameter of 280cm?
did siemens build props for other engine manufacturers?

best regards

Sven

I don't know about the propeller, but that seems like a VERY high pitch (430 cm) for a propeller that size.

Maybe Bob Gardner will have some information, and I'm not at home right now to look through his books on German propellers.

Thanks for the hint with the unbelievably high pitch. As I read a lot of stuff about wooden propellers in the last days, there's a second hint: My propeller has no bolt holes.....

That often means that it was rejected late in the manufacturing process and never got to the final drilling.

Can you post pictures of it?
