Thanks for the info…
I’ve seen a few older posting with pictures of the paper label inside a PR 350S. Most of them state Epiphone by Gibson, Model info, then serial number, then Made In info. However, mine just list the words Epiphone, Model & Serial No., nothing else. I purchased the guitar new in the early to mid 80’s, in the SF bay area. It has a 7 digit serial number, beginning with 9082, so I don’t think this a manufactured date…
