Tom , Shutterfinger , Bill,
I contacted with seller , a shop from Holland and he said to me lens is perfect and there is no dent , spill , bump , scratch on the body. He says there would not be any problem but camera is not tested.
I contacted with Leica Germany and waiting a CLA quote.
I think I got it about micromotors. There is a Leica distribütör and their repair person here , now I will write him. At least he can find the schematics and Leica advise.
Bill , as Bolex it is. There is two sections , one with mercury battery , one with 4 AA batteries. I will report back with the replies since all Google read this.
