I think it looks like a TSS-38, a Silver Star with an alder body, maple neck, round-lam rosewood board, big headstock, three bolt plate, tuners look original. This would be one of the lower priced models, which you can confirm by reading the catalogs on the Registry site.
If the frets are not too worn and the pickups are original you will have a good sounding CBS-era Strat replica on your hands. These are not especially desirable to Strat collectors and other purists, who tend to think that everything Fender made after the CBS acquisition was junk. Therefore, in their eyes, a Japanese copy of a less-than-desirable Fender product line is something to be avoided.
Many collectors are beswoggled with small headstocks and four bolt neckplates, and tend to laugh to scorn the CBS-era stuff. If you happen to like the slightly more narrow neck widths and big headstocks and don't care what the collectors think, they can be bargains - but they will probably not increase much in value. But if you want a good player, that's not a bad thing.
They are rare outside Japan (they were only released to the Japanese market, as far as I know) but that doesn't necessarily mean they are worth more because there seem to be at least three or four of them put up on Ebay every week. They are worth a bid but like everything else it'll be worth what you think it's worth, and playing-wise, I doubt you'll be disappointed should you nab it. Rosewood boards seems to be more desirable to players for some reason, so it may cost a bit more than an all maple neck.
Hope this helps.
