I have a light Blue DeRosa - I think about 1976
Super Prestige Pernod sticker with 1975 worlds on it
BB has top cable guides, and the shell has a heart cut in it.
All lugs appear to be dubois, built-up in areas and filed to fine points
Chain stays are round to four sided diamond to round
No top tube guides
short reach brakes
No serial number
Fork crown is flat, a heart outline in it, the tangs have two rectangular arrow head cut-outs.
