Help please identifying an adapter.

This side is female threaded M44, and the outer bayonet is 50mm



The rear has male M44 thread. The only marking is Japan, and a flat spot with a small red dot for alignment.

I found reference that M44 fits (at least some) Zeiss telescopes. The bayonet might be for a Miranda?

Miranda extension tube part

Looks like M42 to Miranda.

Some Miranda models also had a M44 thread and also a bayonet on the same camera! Odd I know but I had one way back in the 1970's. Actually Miranda's were quite nice cameras to use. I think they used lenses made under the Soligor name, but I only had a prime 50mm F1.9 with the bayonet fitting. The others were Soligor with a interchangeable thread mount, usually called a T2 with a manual stop down ring
