Thanks John. I think you made a good point in suggesting that the second and third screws in from the lens mount are best left alone. And probably the roller screw too. Wouldn't it be fun to be let loose in a Leica workshop for a day? The fella over the road completely disassembled his Canon EOS 750 a few years back, on the dining room table. Got it back together, no screws left over, works just fine. He's a diesel mechanic with the bus company. I might give him my M6. It'll come back chugging along well at low speeds. Regards Rick Dykstra
