Ebay mystery thing……..

[Rik ShawParticipant @rikshaw]

This item has only a few hours to run on Ebay. I have studied it at length but cannot come up with any explanation as to what it could be used for. The two micrometer thimbles make it even more difficult.

The only thing I can say is that I do not think "lathe" should be in the description, I rather think it is part of some sort of measuring instrument and judging by the quality I would suggest pre-wall Russian.

Fancy a guess?

This looks very much like an attachment for phase viewing of polished surfaces off a microscope. Basically a rotating translation tables so that the facets can be seen in different types of light.

Possibly as suggested for metalurgical or polished grain structure.

Spot on Clive, a few years back I sold a laboratory microscope bench equipped with every conceivable bell and whistle, (ex RN Dockyards Rosyth) it too had a a couple of very similar pieces of apparatus!

It is the stage from a Vickers projection microscope, used to mount the specimen to be viewed. The microscope was of the inverted type so the object to be viewed was mounted above the objective and the image projected back to the viewing screen or eye piece . The two rows of holes at 90 degrees to each other had fingers attached and if a specimen was marked with a datum edge it could be removed and replaced in exactly the same position in the field of view or moved via the micrometer thimbles and returned to the same place again. Obviously the stage could also be rotated if required.

Thanks for all the replies and especially for Max T's obviously knowledgeable description of the item.
