Hello, I am hoping someone can help with this guitar.. my uncle has had it since the 60's and said his mom got it at a garage sale for him.. all we know is that its a supro and has pat. pen. on it.. the serial # is x30478.. I just saw a supro ranchero picture on a site and it kinda looks like that but with a different headstock.. I hope someone can give us a little more info about this guitar.. Thanks
Tony
