Restoring a foldable vintage camera Moskva-1

In a nutshell, I tried taking it to a vintage camera repairman, but he kept on bringing up weird excuses to not do it. So I decided to do it myself with the tools I have. Hence the improvised solutions.

"The Moskva-1 was the first Ikonta type folder made by the KMZ factory. ... This model was in production at the KMZ factory for only 3 years, from 1946 to 1949. The camera uses standard 120 film and produces eight 6x9 frames. ... Moskva-1 is quite uncommon and hard to find now."
