What Mount Is The Hanimex 300mm f6.3 Reflex?

[xaprb]

I’ve recently acquired a new mirror lens, and although every citation I can find on the Internet says it’s a T2 mount, it’s not. The lens’s thread diameter measures 47mm and I believe the thread pitch is 0.75mm. I can’t find a camera mount with those dimensions! See attached photos. It came with an adapter labeled CS, which looks like it adapts to M42 mount. (What does CS mean?)

Chinon CS mount, which is essentially the same as M42

47mm is perhaps Hanimex H?

CS can also refer to Contax Screwmount, also same as M42.

That sounds like exactly what I have. Thank you!

Could be a Komura Unidapter standard. Their M42 adapter is labeled "CS".
