One of them is a true Vintage Guitar as defined by the forum rules- although I can't find much info about it anywhere. Most sources (similar listings on eBay/Reverb, a few cryptic references on some Univox fan pages, and a couple of YouTube video demos) that I've found say that it is from the '60s, but I haven't seen anything that points to a model name or firm date.
Anyone have any insight/experience/opinions on these?
Took the neck off (and the 4 strings that came with it) and opened up the guts- there are NO identifying marks or serial numbers to help with the date or model- even the pots have no date code. "Steel Reinforced Neck" on the neckplate is about the most informative text found anywhere besides the logo, which puts it from the Matsumoko family of Japanese-made guitars. That's as far as I've got with it.
I'm trying to decide if I should restore it as much as possible to Vintage spec, or if I'd rather refurbish it and rock it as a player.
Vintage restoration route: Daunting. a) One of the pickups isn't working and a look at the wiring seems to show everything intact. b) plastic nut is in bad shape. c) frets are worn and even damaged in a few spots- a refret is almost certainly needed. d) switch tip is missing, as is the trem cover.
Player revival route: Less daunting, but also maybe less rewarding. I'm thinking along the lines of a black anodized guard with lipsticks or even Jag-style pickups (I don't want to route.) I think it will still need a refret to get it up to grade, but that's probably last on the list.
That thing is art- if it were mine, I'd do what it takes to get it functional in its original state. If you decided different pickups are in order, no doubt it could be done reversibly with a new guard etc. I hope you take the preservation route first. FWIW, a friend of mine has had those pickups in a few guitars and thinks they're the business.
