Wow...thanks, that link answered alot of questions for me. I love these particular guitars because they are cheap and still in fairly strong supply. I've bought and sold dozens of them and the really good ones are really pretty good. I have managed to hang on to several and now I'm going to try to find one of each FT-. Not all of them made sense to me the way they were marked......some have no serial number, many have only a model number and no "style" designation. I have one that doesn't say "Kalamazoo, Michigan" under "Epiphone, inc." on the lower right of the label. Still sorting all of this out.....thanks again
