Lugged Aluminum Tomasso is a rebadged Alan brought it by Ten Speed Drive Imports (out of business now).
It is a "glued and screwed" aluminum lugged frame, meaning the lugs and the tubes were threaded plus they were also glued.
Back in the day, they were described as "lively" or "whippy", depending on your fervor for steel bikes of the same era.
The same frame/bike was also badged as a Guerciotti and, if you haven't guessed it, Ten Speed Drive was also the US Importer of Guerciotti bikes.
