Looking for a few repair manuals (7SII and Yashica GSN)

[Shaocaholica]

Anyone know where I can download/buy repair manuals for a 7SII and a Yashica GSN? I just want to clean out the RFs which have gotten a bit dusty and foggy.

As for your GSN; Here is a site with some good photos of the disassembly process. It's not a manual but, it may be of use. Also, you may want to contact Joe, the "Yashica Guy" and/or visit his web site at yashica-guy.com. Good luck.

Repair manual for the 7S2:http://www.oldtimercameras.com/stock/Model.asp?Model=7219&ModelPage=true (http://www.oldtimercameras.com/stock/Model.asp?Model=7219&ModelPage=true)

Any time you need a repair manual for a vintage camera, Oldtimercameras http://www.oldtimercameras.com/Default.asp (http://www.oldtimercameras.com/Default.asp) and Craig Camera http://www.craigcamera.com/ (http://www.craigcamera.com/) are probably going to be your best bets for finding it (each has a huge inventory of manuals).

Be very careful when cleaning the rangefinders. The semisilvered mirrors (in front of the viewfinder) can have silvering that is incredibly delicate. Anything more than a gentle puff of air touching them can (and probably will) remove that silvering. The silvering is usually deposited aluminum vapor (it was cheap); if it's oxidized, it will crumble at the slightest touch.
