Having a couple of Billato built bikes myself, and having spent too much time researching Concorde stuff, it occurred to me that I had the beginnings of a list of Billato markings for which frame material was used.... So I did some research, asked a few people in specific cases (many thanks to those people) and have come up with the following list. The list seems applicable roughly to 1986 lets say to nearly 2000 I suppose. If any of you who have a Billato creation can add or correct let me know and I'll update what I have in this first post. And a disclaimer, I have no intention whatsoever of becoming a Billato historian, ain't nobody got time for that.

For those that don't know Billato built, in that sort of era, for Tomasso, Masi, Guerciotti, Concorde, Giordana, Lemond, Marin, Look, Fondriest plus others I'm sure.

Example of a typical format, size and tubing. List follows below, with explanations where I am not sure. I can't make any claim that these letters were used consistently through the whole period, but it is hopefully a useful resource for someone nevertheless.

?? MAX in theory there should be one for Max (if we assume Billato built Max frames) but I've never seen it.
B SP this one I'm not convinced that the one example I've seen is a Billato, even though there's an argument it should be.
NO Neuron, based on a Look I've been able to examine (small sample size so far)

Excell tubes:
GLX GLX verified by fb user Doug H, thanks

GL GL a bit of a guess, not seen this myself, makes sense in theory

Chromex and Podium I'm no expert on the Excell tube line , unsure if Billato used these 2 much or at all
