The light meter cover has holes, the light meter setting looks like a Contax IIIa or a Kiev 4, but also somehow different.
I've never seen a camera like this before, what might it be? A conversion in the 50s, because, yes, why? Or a prototype? It is from 1938, as you can see from the G serial number.
Have a look at the pictures, I will take it apart soon to see more details:
