I've put lots of clunkers back into playable condition with not much effort. If you wanna play the giant 6 string uke, make the missing parts and go! Seen lot's of junk like one with a trapeze that was missing it's bridge and nut. That was easy to make into a giant 6-string uke again. (But I did do a 1955 Martin that had been left in the case for 30 years and was moldy and the finish was totally all cracked up, but I made it play again after making a new nut and made it look decent after polishing the bejeezus out of the 50 year old lacquer.) If it's broke, like torn wood and everything, I'd use it for parts. Separate it's parts, remove the braces and you might have some good wood to make a real instrument out of!
