Congratulations on another Legnano! Let's see some pictures!!! I have seen a few with Reynolds 531 decals, but they were always the older ones with the "hot dog" shaped painted down tube logo, not the squared off decal. From what I can gather from looking at different examples it seems like they switched from painted down-tube to decal in 1971 or so, so maybe that will help. Other than that, I have also seen 80's examples when they switched logos again on Roma's that had full Reynolds 531DB tubing (like the Fondriest team bikes). So far I have not seen any 70's bikes with any tubing decal at all, just the Emilio Bozzi decal above the shifters and the 6 volte sticker under the seat binder.

I have a clear memory of a white legnano that I was looking at for pictures of the infernal universal rear cable stop that belongs to someone on this forum that has 531 stickers on it, but I have been looking and can't find the pics. Anyway I can't wait to see your new bike.

All the best, Devin
