The problem is you are asking legendary pro bike money for something with its share of problems:
The new paint job is wrong. Decals while mostly correct (if it weren't for the mix of Master Piu and Master Olympic) are in the wrong place/on the wrong tube.
You substituted with a more or less modern wheel set, which means no Record hubs/cassette/quick releases.
Ditto the brakes, those would have either been the Deltas, Cobaltos, or Monoplaners instead of what judging by the adjusters are, lower tier brakes (thinking Mirage or Veloce here)
Seat post should have been a C-Record or Record Dart, but on the bike is something cheap and Kalloy-ey.
The early 90s were when the Master transitioned from the Master (Piu) to the Master Olympic. I kinda wonder if the guy didn't sell you an Olympic model as an Olympic team bike either because something got lost in translation or on purpose.
And the number tab is where you fix your race number to the bike
In my eyes you are asking 7.5 K for a 2 K bike.
