I have the physical catalogue in my collection. I'm happy to share it once I have finished the photographing, cropping and collating of it (which is underway). My Squadra, which is older than yours is a Billato build, and apart from Campagnolo vesus Ultech dropouts is more or less identical (and SLX vs TSX). After somewhere in the mid 80s, post Cicli John <<Ciocc>> era, all the high end Concordes were made by Billato as far as I know. A Billato made Squadra in TSX is very desirable...... There are at least 5 different builders that built Concorde branded frames at different times. Interesting fun fact, the Italian flag braze on on my early Cicli John <<Ciocc>> Concorde is a subtly different part to the one on my later Billato, and not all Italian made Concordes had the flag braze on.
