I've also got the mystery MR factory code on mine - sorry can't post pics at the moment but it has a made in Korea sticker on it, the rest of the serial number says it was manufactured in 09/2001 and number 0334. It is an Epi LP Extreme - White Pearloid top. I've found that all other Epis of this particular finish also have the MR factory code. I read that Epiphone were contacted directly and they said it could be a misprint and it was meant to be MK (Muse, Korea) but I find it difficult to believe that they'd get it wrong on a lot of guitars. It's a mystery!
