I have one of the older Zorki 4's.....from 1958. I observed looking at my film strips that frames are not 100% symetrical. I have about 1mm from the top of the sprocket holes and at the bottom the frame goes a tiny bit into the sprocket holes. I did an investigation and found out that the film canister was correct in place. But I also observed that there is a 0.5 - 1mm thick spacer placed where you insert the film canister. I could look like if I was able to remove the spacer everything would be ok. Do you have this spacer in your vintage Zorki's 4? ....and do you have same "troubles" like me? 🙂
