Thank you for the excellent photographs Matti.

I have answered this question before, recently. Perhaps you emailed me direct.

The diameter of 3050mm and pitch of 1720mm suggest a heavy slow moving aircraft. Your prop was fitted with a quick release hub designed by Rupp. It is likely that it was used on the Junkers F13a, a civilian transport aircraft, designed at the end of WW1. Early versions used the BMW 185ps engine.

It has a value today of 1500.

With kind regards,

Bob
