Canon F-1N Film Camera Body Only Not Working

Serial Number: 148640

Body only. No Finder

In beautiful cosmetic condition with wear mostly on the bottom plate but the camera doesn’t recognize batteries and will not work when one is installed. Actually, if you wind the film and then insert a battery, the shutter will fire for one shot if the lens is not in A mode. So the camera only works in mechanical mode at a fixed speed. All other functions appear to work well..
