I got the CCN working today. I took apart the camera to clean the range/viewfinder, and to lubricate any gears and moving parts which I could find. I put in a new battery, but I got no light when pushing the battery check button. Cleaning the electrical contacts solved the problem, and the camera is now firing at all speeds. I put a roll of film in it a few minutes ago, and if the weather cooperates tomorrow, I'll run the Acros through it and develop it before I go to work, hopefully I'll be able to post some sample pictures tomorrow evening.
btgc, these cameras are common out here. I stopped by the junk shop on my way to buy a battery, and I found no less than 4 Yashica Electros (GL, GT, GX, and a simple "Electro 35"), a couple Canonets, and half a dozen Minolota Hi-matics. They ranged in price from $10 to $30.
