It is sitting backwards….flip it around. 🙂
Those big wings/elephant ears on the side mount to the main frame just as in clint’s photo.

I suppose it IS possible it is a Bf110 armor glass frame. It looks similar.

Could you get some photo’s with better light? It is a bit dark.

Hi
I will try and get some better photos over the next couple of days.. Cheers again.
Brad.
