Here's a couple I found for sale.
Don't know what those numbers mean. They don't correspond to any of the Gibson serial number schemes that I find. It will probably take an expert to determine the true date. Anyway,very nice  Gibson mandolin. Not one of the higher end models, but it will probably play and sound great with a new set of strings and a good professional setup.Statistics: Posted by Spud1950 — Wed Jan 27, 2010 3:54 am
