I would strip the blue bike first, check the weight of it, and if it's under 2 or 1.9 kg, then I'd consider giving it a new chance to live. Parts seem mediocre so it's not a top model I guess if they are OEM ones. Rack eyelets on dropouts are also used on cheaper stuff.
From the brazing and the details it can be an Italian frame, is the BB-shell 70 mm wide? If it is, then it can be easily made there. Is the headtube 1" or 1 1/8"? The hidden top-tube cable routing is quite weird and gives corrosion a great chance to write the frame off sadly.
An Italian company called FRM made quite a few Ritchey copies in the 90's, they are really nice ones though. Even the R' Plexus model was copied and I don't know why they used the same design straightaway, maybe there was some deal with Tom in the background, who knows.
If you post a thread in the MTB chat subforum, I'm sure somebody can help with the identification.
Cheers,
Endre
