I have just bought this frame off eBay, and I wonder if anyone could help identify the maker or brand please? It has got Reynolds 531 decals, but I have no idea if the frame really is made from this. The cantilever brake bosses would suggest a touring bike, but there are no rack or bottle braze ons. The forks definitely have Brev Campagnolo drop outs, but I can't see any of the same on the rear. To my untrained eyes the seat stay lugs are a bit different to most I have seen before. Also there are rivet holes for a head tube badge, so I'm assuming that this was removed and the frame resprayed. It is very light weight, so could easily be a Reynolds steel frame. Other than that... All help appreciated. Thanks. David
