Hi,

I Need help to identify this huge wood Propeller
11 feet and 10 bolt (3,40 MT)
No id Number or any mark

You can't without markings.

The diameter measure Is not usual, or i am wrong?

Only by Ratier, there were 16 different 3.40 meters wooden propellers. So, perhaps one hundred in the world.

Ratier made 116 different wooden propeller serials larger than 3.40 meters between 1925 and 1936. The largest was 4.40 meters (~ 15') made for Potez 34-1:

An Airship prop maybe?

It may nearly impossible to identify without stamped drawing numbers. I suspect that it's a factory reject
