Zorki 3 / M With An Issue

I found a Zorki 3 or 3M can't remember for sure what version it was at a local flea market where I bought my FED 2. Clean camera by has a sticking shutter. Seller wanted 40.00 CND for it. Most likely I can get it for less. How major an issue is repairing it. I have basic skills and have repaired a lot of my own RF but mostly with Copal shutters.

What is a fair price for the camera? Thanks

Had a look at it today. It's a 3C version.

Hello John,
What do you mean with sticking shutter? If the curtains are OK, but you need to clean the shutter only, you can do it even without the complete disassembling the shutter. It is good described on I-site DVDTechnik http://www.dvdtechcameras.com/info/2.htm.
If you need, I have an English manual, how to replace the curtains on Zorki cameras.

P.S. I have bought my Zorki-3C in mint condition with case and passport for 50,- USD. I think it is fair price for it.
