Will post pics tomorrow, promise...
Anyways, did the rear brake callipers this afternoon. They were more tatty than the front (not surprising, really), but again, it's a cosmetic thing rather than a structural thing. But they've come up reasonably presentable, so right now I'm not too fussed.
The issue with both front and rear is that the lacquer coating has come away in places, and since the callipers are made from pressed steel, rust is (and will be) inevitable. Also re-installed the rear brake cable hanger.
One thing I will need, or rather two, when I eventually get round to doing the cabling, are the doodads that connect the cables to the callipers. Those currently fitted are rusty and pitted beyond salvaging, and on one of them, one of the hooks won't engage because part of it has sheared off.
With things going back on the frame, it's starting to look like a proper bicycle again. I plan on ducking into my LBS on Friday, as well as another place I've found locally that also does bikes, to see what they've got in the way of bars. Budget alloy will do, it doesn't have to be anything fancy.
