    1. Sorry, this is not a selling site and the guitar is not available. Occasionally I make an entry for guitars that are for sale. In those cases I make a note at the bottom of the description with a link to the dealer’s site.

      I have no affiliation with any of the dealers. This site is only meant to document Martin guitars as a reference to collectors and dealers.

          I don’t have a lot of info on Levin guitars produced under Martin ownership. However, I did find a few warranty records from 1970 to 1977 but the serial numbers only range from around 525400 to about 538000.
