Beautiful Masi, I like these late 70's/very early 80's Italian bikes as they were still quite conservative with their graphics and paint which makes them look very elegant compared to the later Italian bikes that became "peacock" bikes, festooned with all sorts of gimmicky graphics, crimped tubing, paint jobs and pantographing.
I agree, the brake system on the bike really needs attention. In its present state, it looks a bit out of place on that immaculate frameset.....
