Much the same as Mike says:-
I had an ML7 belt cover matched with a Dulux machine in a DIY barn (B&Q). The resulting shade was nothing like the original sample, other than being grey. It was used to paint a stand that I'd bought in a slightly 'foxed' condition, that needed a fair bit of welding.
I've got a tin of Myford grey (made by Trimite) that I bought from the stores at Myford's Beeston works but, as yet, I haven't opened it so I don't know how good a match it would have been for my 1967 lathe.
I suspect that not only does the paint change over the years, but that the original paint colour may have drifted with time as well.
If the lathe has been completely stripped, then just use whatever colour takes your fancy.'Dove grey' is a shade to look for that's close. By far the most important part is the high-build primer or filler that goes on and gets sanded flat before the top coats. Without that, the castings look as rough as castings!
