I cleaned up a bit the Duravia frame that Alex identified as one of the marques made by Mecadural. Checked the wheel size, thinking it might be 650B, but not only does it take 700C, but even with the 700C wheels, it has huge clearance, requiring very long reach brakes. Don't think any brake from the 70's will reach this long, even if they were correct, so I think I will have to look for for old very long reach brakes, probably French, with French eBay being the most likely source. Can anyone advise some of the brand names of 40's/50's French brakes that I can search for on eBay?
