The frame is probably at the higher end of Maruishi's catalog, although the brand itself doesn't have a tremendous amount of panache in comparison to some other brands in that era (Panasonic).
I'd fix it.
I'm assuming a frame builder could braze new tubes on, and set proper geometry. Then there would be the custom paint/decal job afterwards. That's a lot of work, and still the chance the paint color would be off. The paint color is the big deal for me. Not sure I'd wanna get into all that. Just keeping my eyes open for another one, and hopefully one day it will be meant to be. Like a long lost family member finding me after a lifetime of not knowing each other. A very special moment in time, if it happens.
