I sold one of my home serviced butter smooth Zorki-1d to a classmate from Tajikistan. She bought it as a gift to her father. She said he was VERY glad to receive it(probably an item he longed for as a youth), but unfortunately the camera would be on the shelf more than it would be in-action.
I recently assembled another Zorki-1 for myself:
Body:
Zorki-1d chassis + Zorki-1c “Bilingual” top plate and vulcanized shell with lens mount.
I bought a beat-up Bilingual Zorki-1c earlier this year. I like the Bilingual Zorki-Zorki engraving, but have not found that the Bilingual version has better build quality than normal versions. Additionally, Zorki-1c's bump-shaped vulcanite covering looks much better than the ones on later Zorki-1d and 1e, to me. So I replaced the top plate and the shell on my Zorki-1d, which has serviced shutter already.
Lens:
KMZ Industar-50 lens block and base + Industar-22 “Moskva” faceplate.
A known problem with Industar-22 and 50 is that many samples tend to give a circle/round ghosting flare when the sun or even overcast sky is above you. I still haven't figured out the cause of such flare, my guess is that the flare is caused by some internal reflection on the areas between the lens groups. The Industar-50 I have is a sample with minimal flare issue among other copies. I do like the "Moskva" name plate on pre-1950 Industar-22 (uncoated flare-kings), so I just replaced the name plate on my I-50 with it.
At last I added an “Elmar 5cm” lens hood to it. (Made in capitalist China, totally tainted the combo!)
