Many Fender copies, I'd assume.
Carvin is 43mm. Vaders are the only exception that I am aware of.
G&L?

FWIW, I doubt anyone's hands can feel the difference between a 42mm nut and a 43mm nut. What really matters to "feel" IME is the string spread, and the string spacing. This boils down to how the nut is slotted. I'll bet if you got a 43mm non-slotted nut blank, and simply spaced the strings a millimeter narrower than most people might do it, you'd like the feel just fine.
