I have an Eumig 16c from eBay. It came with bent lens turret arms, a faulty film speed selector dial a
an interior detent arm that prevents lens selection when the main lens is in any other position except
infinity focus. Well, (patting myself on the back) I disassembled it, did lots of cleaning lubrication, straightened all the bent items, put the lenses back in their proper seats and it is now purring loudly.
I made a test film for focus, iris operation and speed. Now I will have to weight for the film to come back
