Its just an imported Les Paul Copy rebranded with the Palmer name. I think they have been importing different ones for a while. You can maybe check here: http://www.palmerguitarsusa.com/
to see if they have any info on the older ones.

Bolt-on neck LP copy from Japan, Korea, or China.
"Your sound is in your hands as much as anything. It's the way you pick, and the way you hold the guitar, more than it is the amp or the guitar you use." -- Stevie Ray Vaughan

"Anybody can play. The note is only 20 percent. The attitude of the motherfucker who plays it is 80 percent." -- Miles Davis
