I'm pretty sure it's a Gibson L-30. The tailpiece,bridge and tuners(looks like they're missing the bushings though) all look correct, however it appears to have been refinished and the "Gibson" logo was put on,but it is not original correct.Is it a decal? The original was silkscreened on. They only came in black and sunburst. Here's one in original condition.
Model: L-30 Acoustic Archtop
Available: 1935 to 1943.
Collectibility Rating: D- (a very basic non-cutaway model).
1935 L-30 introduction specs:
14.75" wide, flat back, adjustable bridge, trapeze tailpiece, elevated unbound pickguard, single bound top and back, dot fingerboard inlays, silkscreen peghead logo, black finish.
1937 L-30 specs:
dark mahogany brown sunburst top, brown mahogany finish on back and sides.
L-30 discontinued in 1943.
You can do some further looking on the net,but I'm pretty sure that's what it is. How much is seller asking for it?
