It's a L6 but much older than other L6 I had. You can see that by the crumbling celluloid binding on the back. It's also missing the serial number. Possibly a prototype build?
It is incredibly loud and very full sounding. A real, serious dreadnought. Don't let that binding situation discourage you - its tone compensates for that. The top geometry is great. Ebony fretboard. Original tuners. Still has the case it was sold in, which will be shipped with the guitar.
p.s. cat is for that photo only, he is not allowed in the guitar room and there's no pet smells etc.
