I have an old Airline Archtop Guitar. A low-end Kay model? Not sure. How old is it and what’s it worth?
I’m not sure on the manufacturer. It has a painted on white purfling around the edges and on the fretboard (dots). Missing pickguard, but finish is still unblemished. Serial# L5758. Thanks.
What year was it manufactured in?
Kays were a department store model sold at Woolworth’s. They were a low end guitar manufactured in Asia in enormous numbers. Unfortunately, because of these three reasons, they aren’t worth a lot. Sorry…
