Not enough info to tell from those photos. Anything under the pickguard that would give it away? It's definitely refinished, so that may have hidden any markings or serials. The fact that it looks like rosewood boarded makes me suspect ESP Japan when they were making stuff for other companies and did some limited distribution lines to the Japan market only. (Even the Japan only Nightswan had a RW board instead of Ebony.)They definitely did neckthru strats and superstrats back then. I'm guessing the age at early 80's from the trem and the pre/dont care headstock lawsuit.
