Hello,

this was sold as Jupiter 12 repair set. A bakelite box with a metal piece inside in which the front lens and the rear lens are screwed in. I have never seen before such a lens kit.

Comes with a passport, maybe someone can translate what is written on it.

Maybe the lens elements in the J12 are a matched set, so if the rear element gets chipped (which it is very prone to considering the exposed nature of the element) then the most economical option is to change both sets of elements. It is a 10 minute job to swap the elements but the shimming to get infinity focus correct may take a little longer!
