Dave Daniel suggested that he maybe should scan and make
a pdf out of his HP3456<<<A>>> manual. I was trying to head
that off.
I looked in the following catalogs:
1986 - 3456A
1987 - 3456A
1988 - 3456A
1989 - 3456A
1990 - 3456A
1991 - 3456A
1992 - 3456A
1993 - 3456A
...
1997 - no 3456 model number in catalog
...
1999 - no 3456 model number in catalog
2000 -
So, if the "B" model exists, it would be in 1994, 1995, or 1996.
The 3458A was the only meter in the 34XX series in 1999.
Searching for HP3456B results in a couple of ChatGPT created
results that don't actually contain 3456"B".
Although the OP hasn't chimed in, I would bet he made a mistake.
I am pretty certain that no 3456B ever existed as a DVM.

I've never heard of a 3456B. I don't think there is one. It'd be very
interesting to learn if that's not so.

Yes. There was a time when a 3458A was on my list of expensive
instruments to acquire for my lab, but I ended up with the 3456A
as an interim solution and it has fulfilled my needs. I wish I
could find a replacement for the small aluminum panel on the RH
side on which the binding posts are mounted because mine is badly
and deeply scratched, but tha's a nit.
It sounds as if i should scan my 3456A manual and upload a copy of
the PDF to the HP Wiki. I an in the process of scanning a
Tektronix 7934 manual (the foldouts are tedious to properly
scan), so the 3456A manual scan would be queued behind that.
Everyone should own an HP 345xA, a Fluke 27 and af least one
Simpson 260, lol.

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.
