my great-grandfather died about four years ago, and I just now inherited a Supro old relic. I'm not quite sure what exact model. but it has a fixed bridge, single humbucker pickup, 1 tone, 1 volume control. non- locking tuners. And a body that reminds me a fender jaguar. oh, and a sunburst color

 Problem- the neck is somewhat warped, in some places it's not bad. But, It's not really playabe  It's a pretty good-looking guitar, it's gotta be about 40-50 years-old. Being there's not much on supro past the 60's. And I'd like to know if there is any real surgical restoration I could do. Like replace the neck, would that work? Oh, and the pickup works, it's fine for now.    

 I'd rather just make the thing playable, not restore it's beuty. How much might that cost? Is it possible?

 I also heard that supro was a rare brand, more of a collectors item. Is this true?
