Well, since the auction is ended, ebay suggested this as an alternative.

Hmmm - the "COS" s/n is Squier, but the decal says Fender.
I wonder which could be right...

Incidentally, I'm always looking out for more unnecessary bits to put in my parts box: pickups, tuners, neck plates, knobs, etc. So if you've got a box of junk it might be worth bringing it along.
So, are they still available? 🙂
Incidentally, I had one I cut for a Rickenbacker many years ago; when I replaced that it was wrong for a Fender, but I found a new set of saddles at a recent event and had them for it; I think the Allparts Kickass parts are compatible too.
