I'm glad there are enough Ron Coopers around to motivate this thread. We're continuing this hijacked thread here.
Here's mine after its repaint.





I bought mine in the early 70's. The RD is dated 70, but I can't be certain it is original to the bike. It seems that there were originally braze on derailleur guides that were removed before I had the bike. I had the bike repainted a couple of years ago by a fairly local framebuilder. Although the original decals were on the bike when I gave it to him, he put incorrect 531 decals under his clear coat. I preferred the brown suede Unicanitor saddle to the currently mounted leather one (also purchased with the bike), but the suede is now badly worn. The small flange hubs mounted have world champion colors around them. The large flange hubs have oil ports. Both sets of wheels have Fiamme rims, but the stickers are gone and I can't remember if they were the yellow or red. I have the slightly road rashed original brake levers, but it is costly to replace the gum hoods. More later perhaps.
