I have one in a much smaller size. It appears marked as a 61 cm but the head tube length would have me guessing more. Many of these were built by Joe Starck. They are well built. I am not a fan of the Henry James "Masi" head lugs, I guess I would want them to finish off at the head tube shoreline more like the previous designs, but the fork crown has grown on me over time and the bottom bracket shell has nice deep chain stay sockets. I have noted that the accent color painted in the lug details varies a lot with how, if and where it is applied. Often the M on the bottom bracket shell is also paint filled.

Most of these bikes got Super Record "reduced", steel pedal and BB shafts. C Record of course is also possible.

I am thinking of what to do with mine at the moment. Toying with the idea of building it up with modern 11 speed Athena.

As far as geometry goes, at least in the middle range sizes, there was a bit of updating by the 80's from the 70's classic geometry. I do still wonder why the bike was originally named Gran Criterium, it really is more of an all day road bike with just a touch higher BB, at 72-73 mm of drop vs classic Italian road 75mm. (yes, the modern carbon design consensus seems to be 68-70 mm of drop)
