have you tried ebay.com or ebay.de. you find a lot more new old stock pieces than on ebay uk. even if there listing says they don't post to the uk, ask nicely and thet usualy help you out. 95% of my bike is from abroad. hope this helps.
im glad you all like it. the tyres aren't so clean now and have't got much tread left either :D . i use the shifters on friction and the gears are smooth as you like but if i use them on indexed it's like a lottery for gears.
im looking for limited edition marin pine mountain (black/dark grey and dayglo orange) with browning suspension forks from the early nineties in good condition. the one i had was 19.5" . so if anyone has on they wish to sell. cash waiting. cheers.
