There's an Industrial 11 version of the -11/70, too:


So the only one missing (of the early -11's) is the /45, but I wouldn't be
surprised if that existed too. I've no idea about the /20 (I don't think the
/20R counts), or the later machines without physical switch registers (/04,
/34, etc).

The paint on the front console inlay (I'm not joking :-).

Other than the /15-/20 (which do have slight hardware differences), none of
the OEM/End-User pairs have hardware differences in the circuitry that I know
of (although the /35 was _usually_ supplied in a BA11-D 10-1/2" box, and the
/40 in the BA11-F 21" - and there are rare counter-examples to this rule).
