Sorry to disagree with the purists. I love Raleighs, but anything from their "seafoam and lilac" era with that much rust is crying, begging to be powdercoated.
I do wonder why folks who want a fixie buy a frame that has braze-ons, though. Someone should make a beautiful little anodized alloy thing that covers the DT shifter bosses elegantly. they could be engraved with "This, too" on the left, and "will pass" on the right.
