David, this is one beautiful guitar! I'm afraid I can't shed any light on your dilemma though.
The model number is mouthful, obviously some sort of descriptive acronym for the importer (I assume LTD=Limited. The rest???)
You didn't mention where you picked this up. Are you by chance Canadian? Those maple leafs are very unusual and likely specific to the Canadian market I'm guessing. There were a lot of Japanese/Mats guitars coming into the country in the 70's and 80's under all sorts of labels, so it wouldn't surprise me to see a limited edition like this one showing up here.
Have you tried the Epiphone forums? They seem a bit more focused on newer models but you might find an historical clue or two there.
