I need a Shimano 600 clamp-on front derailleur, 28.6 mm or 1-1/8". (the one with the little green/blue color bar.) NOS or almost. I have a very nice Campagnolo Super Record front derailleur clamp-on 28.6 mm that I'll swap even up. This one looks like it might have been shifted maybe once or twice. Or I'll PayPal you for your Shimano.
Thanks.
