:D Hi mate are you still looking for the Iron Barrel for the Chopper, if so I have a barrel and piston sadly not a spare export head, but a smaller (same comp) head is available. I do have the correct motor alas I think my AJW (Giuletta) might miss it although there is a complete AJW on ebay at the mo, let me know mobs are 07782 212030 or 0796664708 cheers Carl PS I think some choppers were fitted with an Ali/steel lined barrel, I have one if you need a pic again not for sale as it provides the AJW with a bit more performance.
:) Further to my las I also have the correct head, it is stamped up Record head rather than as I previously thought (Export). That was the similar head fitted to the later ‘big stud (?)’ minarelli’s, let me know, Carl
