I have a 1980 Masi GC which was built with 5-speed and 120mm rear spacing. I had it opened up to 126 (at Schwab Cycles in Denver, CO) not long after I got it (about 1986), and have used a wide range of 7-speed freewheels (not cassettes) on it with no dropout chain rub issues. It's all NR, friction shifted. Tubing is unknown, but standard diameters.
It also uses 27.2 seat post.
My 1984 (or so) Mondonico in Columbus SL came with a 126 rear spacing, and an Ann Arbor shop opened it up to 130.
No problems with either of these alignments and cold-settings.
