I think this part number originally came with a silver label, but not 100% positive. Also I have a keyboard with this part number which has an Allen Bradley silver badge...
Since yours is the only other example I've seen, this p/n may have been for an OEM variant where IBM made custom badges, the customer added their own, or the logo area was left blank (like the 1397735,
shown here).
Forgot to update the last thread, but I bought the Industrial M posted a couple weeks ago which was missing the label. Well, the bad boy came in and I found something interesting...
Huh? So they sent you a different Industrial—a later one, with oval logo on left? It can't be the same p/n, can it? How about including a photo of the label? (No label photo... And you call yourself a keeb-head?? LOL)
