Hi: I have a "Vibra" F Style Mandolin in the shop for major repairs.
No tags or serial #. Just Vibra on the Headstock. Appears to be solid spruce top with maple back and sides. Gold Hardware with a fern inlay on headstock. Golden Brown sunburst finish. I am guessing it was made in Japan. Lady who owns it claims it to be 80 years old or more. My guess would be possibly 30 to 50 years at most. Any info appreciated. Thanks:
