Thanks for the replies guys.
Actually the humbucker re-routing is not necessarily a deal-breaker for me. I'm looking for a player's guitar rather than a collector's piece so I'm not too bothered, as long as it's reflected in the price.
Likewise the pickups. Since it looks like the guitar has already been messed about with I would have no hesitation in changing them to something more suited to my style of playing, if necessary.
In fact I did the same thing with a Rosewood board '84 Goldstar ST55 which I bought recently. It had already been modified. Here are some pics of how it looked when I found it:
The original gold finish had already been stripped '
'
The previous owner patched up a few dings in the body with wood filler so was probably going to respray it, but seems to have lost interest before finishing the job.
Some other changes had also been made, as you can see.
I've never owned a Tokai before, although I'd been reading lots of good things about them (mainly on this forum!), so I didn't really know what to expect.
It was in a sorry state, but acoustically it had an amazingly resonant sound and feel, so I snapped it up and I'm very glad I did.
I had it cleaned and set up so it played nicely. However, the VI stamped pickups just didn't do it for me. They sounded weak and puny and just didn't deliver on the promise of the guitar's acoustic sound.
A mate of mine has an original '63 Strat so I compared the Tokai with that. His guitar has a really nice even tone, with the top end sparkle you'd expect from a Strat, but also lots of presence in the bass and mid tones.
There's a new company recently set up here in South Wales making boutique pickups, so I asked them to wind me a set to my own specs, trying to get as close to my mate's '63 Strat as possible.
Here's the company. They're so new I don't think they have a website yet:

Fitted with the Radioshop pickups my Tokai now sounds incredible. I'd say it's so close to the sound of my mate's '63 that there's hardly any difference.
For ?300GBP I'm well pleased!
Next I'm going to install a bone nut and have it refinished in a vintage early 60s colour. Maybe Sonic Blue or Olympic White, or maybe even restore it to its original gold!
Anyway, sorry to ramble on. The thing is I'm so blown away by my rosewood board Goldstar I'd now like to try and get one with a maple neck and board. I'd go for an '84 or earlier because I've already seen for myself the quality of those instruments.
So that's why I'm keen to try and find out about the natural one on Ebay. If it turns out to be kosher, even if it's been modified, it might be worth investing in as a project, at the right price.
Jacco - thanks for the advice about uploading pics. The Ebay seller has sent me the additional pics in a format that can't be downloaded. I've asked him to re-send in a different format so I can hopefully share with you guys. So watch this space.
