Kelly Pro Floyd nut size?

[mccullpl]

Hey all, I've searched, but haven't found my answer...My friend has a Kelly Professional (no neck binding, dots), and needs a new Floyd for it. He doesn't know anything about guitars (just how to play them), so I'm trying to help him out. I measured the nut, and it's 1 11/16", but is it wide or narrow string spacing? (R3 or R4)?

Thanks!
Pat

It says if it's R3 or R4 under the locking nut, so unscrew it and take a look!

Man, why didn't I think of that!

Thanks!
