I had asked a lot of people and made enquires all over, luckily I found a mk2 which was re- painted and re-chromed 95% all done but not assembled. Anyway I have it all together now, but its chainset is the weak link, very clean but a little scratched and quite out of true so the chain is not running sweetly and will drop off if back pedalling. I will spend a quiet night trying to improve it but I think it will take a lot of patience and a certain knack
It should straighten out satisfactorily with a little patience. If not there's usually some for sale second hand, just be careful not to buy a shopper/rsw crank by mistake (unless you want the longer cranks).
