I've never been a PRS guy myself NTTAWWT.
There's not much official info on these, but the story is that Gibson was planning to put out a line of guitars called the Nouveau in 87. They were to be milled in Japan then sent to the US for assembly and finishing so they could put Made in the USA on the headstock. Those plans got scrapped, and instead Gibson decided to mill them in Korea and release them as Epiphones. Some people think they were assembled in the US, but others believe they were totally made in Korea. They were made for less than a year and then production stopped. There's some speculation that PRS had threatened to sue.
Most of these were made with Steinberger tremolos and locking nuts, which was a poor design that broke easily. Gibson had just recently bought Steinberger, so the trem units were probably leftover parts Gibson wanted to use. Some believe the three-piece mahogany neck thru bodies on these were also leftover Steinberger parts. This one came with a Strat style bridge that they switched to shortly before ending production. The fretboard is ebonol, which is a synthetic material kinda like what bowling balls are made of.
Here's a shot of the back and the headstock. I can post more pics if there are any other parts yall want to see.
