New here so forgive me if this is in the wrong place. On the internal threaded end is m42. The opposite is 52mm i think by a vernier gauge. Heavy bronzed metal. Came with a bunch of m42 lenses. |

Just a guess but it looks like a lens extension tube with the male M42 mount missing from the 52mm end. Going by the length of the tube it could be a special tube for converting a 1:2 macro lens to 1:1. |

I've got a similar mystery mount thing in a box somewhere, I suspect its a dedicated microscope adapter. It looks very useful, if only I actually knew what it did!

Because of the auto mechanism i.e the rod, running down the middle its highly unlikely to be a microscope adaptor or any kind of adaptor like that. a puzzlment.

the bronze sleeve has a step at the 52mm end. The inners can only go in from the opposite end and have no thread. |
