Just got a nice example of an Agfa Selectronic S rangefinder. Trouble is, I'm having trouble locating a manual for it. Wouldn't normally need one, but the design is so quirky I can't work it out. If anyone has ever owned one of these, could you enlighten me as to what the R and V levers do on the front panel? And how on Earth do you rewind the film? There's no normal rewind knob.
Finally found a manual, so for the sake of future reference I'll answer my own question. The V lever is the self timer. The R lever is the rewind clutch; with this engaged the film advance action is reversed, so winding on as normal actually rewinds the film into the cassette.
