Device with a rotor on top

Hi,

a very difficult one, at least for me. Please have a look at the enclosed photo: it was probably taken in the early fifties in the Munich area, Germany. Nothing further is known.

What is it? Any idea?

Many thanks in advance.

Ahhhh, yessss, ...the Kamov Mk I

Don't see any obvious powerplant, yet the tail wheel seems carefully sprung.
Maybe a drop test mockup?
