Hi folks,

I have just put my K-3 through a disassembly and cleaning procedure and removed the loop formers as well. Prior to that it was scratching my film all over the place.

Now, I have only two major occurrences of scratching. You can see both in the attached picture. The longitudinal scratch on the top is where the perfs would be and so be a non-issue in R16, right? If I can I'd like to get rid of it nevertheless. But what about the ones in the middle of the image area? What might be causing these?

The scratching from side of emulsion ?
If we have scratches from emulsion side.
The longitudinal scratch - i think, need check of film gate detailed, and re-polishing.

The middle scratch - can be - big size of upper loop. The upper loop must be small.
And need check of condition and position of plates between small rollers round of cog's wheel.

If this from side of base, I think, the longitudinal scratch - can be from leber of film counter or pressure plate of film gate.

The middle scratch - from plastic parts of post , what have of spring for press on pressure plate from side of cog's wheel.
You can compare of version of post of Krasnogrosk-1 and Kranosgorsk-3 cameras.

Thanks, Olex! What do I do when I have found the parts that are causing scratches? Polish them out? Using what?

Thanks, Dave
