I got a Yashica C off of eBay that still had a roll of film. After a bit of research it seemed unlikely I could get C-22 film processed. I developed it instead with D-76 developer and ended up with several B&W exposures. No idea who these people are but seems to be early 70s. The building in one was suggested to be the California Capitol. Thought this sub would find some interest that it did develop.
I'm just staring off in the hobby of camera repair, and have been working on a Mamiya RB67. with the 65mm f/4.5. I managed to take it from non-functional to working, but there is still more to learn. I got several PDFs of the RB body and what was labeled filename wise as a Lens service manual. The lens PDF is only a parts catalog, and the various places across the web I find the same download, not an actual service manual. This was very useful, but I was hoping something could help guide me more on any factory measurements especially any specific places for lubrication.
I used the general concensus here of light grease if sliding, and watch oil if rotating, but left the shutter blades and actuacting ring dry. Shutter speed at the 3 fastest speeds seems to be about half slow. My goal is to return it to as close to spec as possible.
<tl/dr> Is there an actual shutter servicer manual for this type of lens not just parts catalog?
