Good repair and maintenance instructions and other technical notes for Soviet camera equipment can be found on many sites on the internet.
Would there be any sense to try to gather such materials into a central repository like this site? Instructions about shtutter disassembly and relube, rangefinder adjustment, etc...
Of course, why not? There is a Technical documents section in the wiki just for this purpose. And I will be adding the file attachment option for the entries in very near future, maybe even as early as this or next week.
