I'm working on a build for a friend who is an avid rider but has never had a really nice frame. The basis for this build is a cosmetically challenged, but structurally sound, Viner Professional, roughly 1981. I'm building it on a budget, so it's going to look like something out of a Mad Max film set when it's finished, and as it is coming together, I realized that I have a nice drive side Sugino Mighty Tour arm w/rings on hand in good shape, but the left, well, I never had one.
Thread and taper condition are much more important here than cosmetics - does anyone have an orphaned left arm in 170mm that they'd care to part with? Something similar looking from the same family would be fine, too. I have some items to trade and can also buy it outright.
Thanks in advance!
