sorry. got a little hasty and didn't see the second set of pictures. The parts are mostly nuovo record, the rear derailleur is a 90's chorus or athena, and the rear hub stuff is all Shimano - you really want to swap those things back to nuovo record, they hurt my eyes. The frame fittings, etc, look almost identical to my Gran Criterium (MC0255, I think), but that came dressed in paint. You need to clean up that crap on the bottom bracket so you can get a good assessment of the extent of the rust.

MC0250, I just went and looked. You'd be astounded at what the bike is worth, I'll bet.
