I love these boards, and it's taking much will power to tell you guys about this one rather than buying it myself (I already have this p/n, tho, dang!):
IBM Model M GE General Electric Medical Systems 2015 PS/2 2054858-001
Seller says "used", but I think they're just assuming that because it's a couple of years old—it looks NIB to me.
I've seen relatively few of these GE-logo boards. They usually say "Marquette" or "Marquette, a div. of GE".
Buckling springs, wacky numpad, etc. Search GH for
marquette for discussions of similar boards.
