Any ideas on this serial ???

[petrochemicals]

Anyone familiar with Korean Peerless (KP) Gretsch Jumbo Ranchers. The Gretsch serial pages don't make sense! Can someone explain this one? #KP04010368 and 201134. I dont know what or where the hell the second number comes from, or even is on the guitar? The #KP04010368 is in the sound hole on the sticker. First two digits are meant to be year, then month, production number blah, blah, but it doesn't make sense???
