Sure. Probably it was a custom shop item (as JP's are now) for sometime. I just wanted to have an idea after hearing Jeremy saying early 90's. Then I might have a real custom shop PG, and that explains things.
I've got that 8,35K double black (no logo) PG in 1991 from a local guitar player, who got it from some other guitar player who supposedly got it from the SD custom shop. No initials nothing, it just has that PGB1 sticker (I gotta double check tho! Was it plain PGB or PGB1) Ok anyway it has no logo and long legs. And sounds phenomenal.
