Not finding any info about the factory code on a 2002 Epiphone Les Paul I picked up on Craigslist. Guitar Dater Project says this: Serial No.: DC02090734 "Your guitar was made at the China, on September, 2002 Production Number: 734 " Weird how it can't tell me which factory, and the QuingDao factory in China didn't open until the following month (October) of 2002, according to an article published by Epiphone. Other details about the guitar: It had a factory "2nd" stamp above the serial no. and the "GIBSON" truss rod cover. I know that second thing could have been added later. Anything special about this guitar? It feels just like both current production Gibson Traditionals I tried out recently. Really great guitar.
