Probably highly useful to those who have the knowledge and courage to delve into the innards of a Minox 8x11 camera (and I am NOT one of those). Perhaps a source of informative data on "how to", if they so wish. I do not advise anyone to attempt to repair a Minox camera on their kitchen table; instead, just contact a qualified repairing shop. I would always highly recommend Don from www.dagcamera.com.
