One thing about these old Marquette buzz-boxes is that they had few moving parts -usually just the power switch (except for the belt-drive units) and a low failure rate .
If all else fails , you can recycle the copper from it's massive coils & leads .
Modern welders have pretty much superceded these old fellas (they're safer , more portable/versatile & so on) .
Perhaps a collector would want your item (it's pretty darn hevi-duty) , but shipping costs would be really prohibitive .... and I'd guess that they'd want a working unit ( who knows , maybe you could sell it for parts , if it's 'dead' , like KC said ...) .
