I came close to picking this up about six months ago, but it went to someone else.
She decided it wasn't for her, and it found me a few days ago. But, I haven't been able to ID it for myself.
I know it's a "Contract Masi" and my guess would be ~92 and either from TSD or Torelli.
Serial number is 09258 and size stamped 64. Can't find a similar serial number documented.
Components are "L code" 87 Shimano 600 tricolor, or 88 Campy "square 41" code.
Friction Campy FD and left shifter, Shimano click shift on the right to the tricolor RD.
Paint could very well be original Imron, but there is no sign of any decals ever, except the USCF badge applied to the seat tube.
27.2 seat post, Columbus dropouts, but no rifling in the wheel stays makes me hope it's SL.
The style and position of the brake cable into the top tube is the same as my '92 Tommaso (Billato), as is the skinny stemmed pump peg.

What do you think? The number format isn't quite like the lists I have found.
If "rare" is based on not being able to find appropriate catalogs, then THAT I got!






There should be some REALLY BIG photos if you "view image"
