OK, I think the neck (at least) is probably a Fender MIJ Contemporary Strat from between 1985-1987. The bridge looks like a Fender system II bridge (you can just see the 'F' logo stamp on the back) but with Graph-Tech string-saver saddles fitted instead of the original. It was made by Schaller in Germany.
The nut may have been a roller nut to start out with (maybe a Fender LSR), which has since been fitted with a standard one.
I'm finding it very hard to find a photo of a Strat fitted with a Series II trem. They probably didn't sell that many of them, with the rockers going for the Contemporary Strats with Series I or III locking trems, and the more conservative sticking with the standard Strat models with the normal trem and natural headstock.
