In regards to frame counting - yes that's a bitch, open the back as if you were gonna load film, see on the seem on the top part where that little metal tongue thing sticks out, that isn't being pressed in enough, it's a bit out of alignment inside, what you can do when winding the film is press extra hard over that spot when winding film on till it hits 1, or attach something there or on the back where it touches that part to push it in a little more.
AN RB back looks like a swiss watch inside, even with the repair manual, I just looked at it, and put it back together without attempting repair.
