Original vintage Valco made Reso-glass right handed guitar. I've owned this guitar for about 10 years. I knew it was made by Valco out of Chicago. All the ones I seen were the Airline models, but they all had a stop tail piece and a square headstock. The only guitar that I seen made by Valco with the neck and tremolo tail piece like my guitar was on the J.B. Hutto guitar, and I knew this wasn't that model. So I did a goggle search and found that there was a Supro version of the Reso-glass guitar that was identical to mine. Same neck, headstock with 6 tuners on one side and the tremolo tail piece. In the time I've owned this guitar I've never seen the Supro being offered. It's in good original condition, and this is how I got it. Treble pickup missing the gold foil. And no tremolo arm. I made an arm out of a piece of metal I had. It's not for dive bombing it's for gentle vibrato no Eddie Van Halen type whammy bar playing with this. It's not made for that and will do damage to the guitar if played that way. Theirs a little bit of crackling noise coming from the input Jack. Might need to be replaced or simply need to be soldered. Comes with newer MBT case as seen in pics. View pictures ask any questions selling as is.
