The wiring looks like stuff I have seen (along with the pickups) on the bog standard cheapo strat copies you used to see in China - often Fender branded. I suspect you may have one of them or even a kit strat - but like you say for 40 quid the neck and body are worth it.
Actually kit would make sense as there's no other colour on it than the blue which was plainly not factory.
I have always got far too excessive with lemon oil. When I first discovered it I was obsessed and did all my guitars including a Tele copy I owned.
It had a maple neck!
