That would be fine for a museum piece, wall art if you wish. I don't know about the guys who built that, I like bikes that I can ride, and neither a 1961 Masi or the replica are really riding bikes. The 1961 probably should be refurbished as a museum piece. If I were building it, I would copy the dimensions and geometry, then using modern tubing with similar dimensions, build my copy, but with a couple of differences, I would build it for modern components. The idea is to have a new bike that rides like a classic one. Before anyone asks, it would have my name on it, not somebody else's name. There is a fine line between a reproduction and a forgery.
