Hello Ad,
As well as a very rare lens (which is likely original to the camera, considering the date) both of your TSVVS cameras are also rare. They are likely more rare than the usual TSVVS cameras seen in collections, auctions, and for sale.
Both have no TSVVS Soviet Military markings or logo. Niether has a serial number. So it is likely that they were never in the hands of the Soviet military services. They may be prototypes and that may be what the engraved "1" that you pictured refers to - prototype or example No. 1.
Also, one of your cameras appears to have a highly mirror polished chrome finish. This is very unusual and may have been the original idea for the finish instead of the normal acid-frosted finish found on other examples.
So, It would be my strong opinion that it would be better to leave the cameras in the condition they are in rather than to devalue them with a CLA just so they can work. There are plenty of working examples of the TSVVS but yours are special and any replacement or alteration of parts could be harmful to the originality and thus the history of each camera.
I have always thought that the probability of these cameras having been designed and produced in Soviet Occupied East Germany, with the exception of possibly having been engraved in the USSR (although the style of the engraving is not so much like other Soviet cameras either).
You have found a treasure trove of museum pieces, so please be careful with them!
Regards, Bill
