did not know you were looking for a Petite Frame. I sold one yesterday! (Rickman one not a Bultaco one) Did not have a swinging arm ,but I have got another new Petite one if required.
A mate has a Petite Metisse frame that isnt being used, so that could go as well if it is needed for a Firko Replica!
(body work not a problem, just choose the colour!!!!!)
