November 7, 201510 yr 4 speed and 5 speed cranks are different , the model 10 had a needle roller little end as standard so the bronze bushed one is probably from a mercurio or similar early 4 speed bike . You could source a crank from a model 16 matador (engine no will start with a 4 )or model 11 pursang which are both very common in the usa and are often being broken on ebay usa
November 7, 201510 yr Author Thanks for that, Bult360. New old stock Model 10 crankshafts are still available, as I've found out. Might have to sell a kidney or two but the option is there. (A new crankshaft I mean!). I did suspect that the rod was not from a Model 10 when I looked at the parts list that Twinshock kindly supplied me with. Well, there is only one item in my letter to Santa...
