yeah, I had one like that too, new around 88ish. Youve fitted different forks tho. It was sold as 531 comp, but someone in the know told me they were built with part 653. TBH for a budget racing frame it was really good and I managed to get it down to around 20lbs without any exotic equipment. It actually rode better than my colnago master for general road races (but dont tell anyone). In fact many friends who had spent lots on italian exotica were p#ssed off that my budget racing bike was much lighter.
The downside of the frame was the overlarge welding blowholes which caused the bike to whistle on descents. In the end, I too fitted different forks to overcome this.
message for LGF - this is the frame type which you acquired earlier this year. yours was repainted black if I recall.
