Lots of replies, I'll try and respond in one post.
The link guitar101 left me is great. It shows 468.3mm overall, and in the second diagram it shows a measurement of 7.92mm for the overhang (I think, either that, or it's the distance to the pickup cavity - but that doesn't make sense).
So that makes nut to heel distance 460.38 mm.
Dpm99, by real, I meant one licenced or made by Fender, and to also address Mickguard's comment, yes, I can make it match any particular project, but I have a couple of different bodies and I thought that if I am going to make some necks, I might as well make one that is the same as the replacement Fender necks you can buy. I can't go entirely by the bodies I have because they aren't original Fender either, and might by different. If they are, I will abandon the idea of "standard" - but I needed that dimension in order to assess what would be best for me.
RAI6, you mentioned the scale length not indicating the length of the neck. If you have a Fender style body that accepts Fender necks, the distance from the bridge saddles to the heel end of the neck pocket, plus the nut to heel distance of the neck itself, should end up being 25.5 inches shouldn't it? I am still learning, so I won't be upset if I am not understanding this.
Dpm99, that Tele sounds very nice. Teles are my favourite Fender. Coincidentally, I was watching a show about guitars on TV recently, and one guy was showing off a very early Broadcaster. It was a bit worn and rusty, and coloured a nasty butterscotch shade, but still impressive, especially when he mentioned that they sell for tens of thousands of dollars!
