They made 3455s, 3456s, 3457s and 3458s. I think but am not sure that these were all "A" models, i.e., 3456A. My understanding is that the 3458A is the (or one of) gold standard(s).
The 3458A is indeed the gold standard, and one of the few instruments to be made with all three names on the front.
I own a 3456A.
They are great meters, even (especially?) by today's standards.
