Don't know much about those either but it's definately old! Very nice guitar! I would take those stickers off though...if you can...
This was Pre Jackson lawsuit for sure!
You can google the old ESP catelogs! It might be in those! It's on the Russian ESP site! Take a look...
Sorry I couldn't help much! Lol
Yeah I started taking the stickers off last night I've just got to work out what's best to use to take of the stickie resadue that won't damage the finish, I was surprised how good the condition of the finish was.
I have looked in those catalogues but can't find a reversed headstock version but I'll look again only had a quick look, thanks for the help any is appreciated.
