I just started work on Masi USA MC 58 041 which I suppose from the SN info provided by Brian is the 141st 58 cm (c-t) frame made. This was sold to me as a 1973 but I suppose it is a 1974. It has a rather nice supposedly Cyclart metallic blue refinish (probably as good as new at least). The frame is rather nice in my opinion. A little extra brazing material here and there but very crisp otherwise. Very stout fork. I guess it is all 531 based on the 27.2 post. Unfortunately I think it was "upgraded" with brazeons- shifter, brake cable, wb and allen key brake fittings. It is 6 speed 126mm also.
Which of these is not original?
What would the most likely original equipment be? NR? SR? Rims? Bar and stem? saddle?
Boy do I hate pulling out a NR seatpost to find a "shorty" 120mm one. Not a big fan of 38 cm wide bars either!
