@Dave F - the FON is 1395. Much easier to see in person, so I can help you there. My dad had already informed me that the tuners were changed, so I'll definitely look at replacing back to the 3 on a plate.
@zombywoof - are you suggesting that the overcoat that is on it may have been done originally?
@tpbiii - I thought the same thing about the logo, but every picture I see online of a 1935 Gibson L-00 has the logo in the same style. Even the L-1 from 1935 looks like this one.
