Received a frame recently and I was curious if anyone has heard of it. I am aware of the Argentine cyclist who started making frames and parts back in the day, but I do not believe this applies to that lineage. It would appear to be from the early to late 80s.
The decal (looks new, without any wear) may possibly be unoriginal although the paint does seem to original. Only decal is on the seat tube; no signs or remnants of decals anywhere else.
Frame and fork (fully chromed, semi-sloped crown) are 531, Cinelli BB is 68cm with French threads. Pantographed fork and seat stay caps with script "L" in a Guerciotti-like star. Top and bottom head lugs, and seat lug have "mickey mouse" logo cutouts; essentially 3 circles overlapping at their edges.
