There’s no way you’re going to avoid a bidding war on this one, is what I’m saying, though it’s possible that posting here adds visibility and increases the chances of a bidding war. The great finds section of geekhack has a large population of lurkers.
I don’t at all mind people posting stuff like this though: we can all watch how high it goes while enjoying some popcorn from the sidelines.
Edit: for posterity, since ebay auctions end up disappearing, here’s the description text and some of the photos:

BM Operator Console Keyboard ?3727? (not sure)
Identifying Numbers : 5640534
Other number:330x-23-14393 (label on back)
Dimensions overall: 4 in x 20 in x 10 in
Description
The object is a terminal keyboard (qwerty key arrangement):
15 pin serial connector
Cable numbers: PN 5640559, EC854949, 453460 (white band on the cable)
circa late 70's early 80's from what I can tell.
This one it very much like a 3727 operators console. Despite the '3727' moniker, that keyboard is the keyboard of the IBM 3101 terminal, which was a standard serial ANSI terminal that worked with things that weren't IBM systems. The dip switches in front are something that isn't that common or at least I'm having trouble identifying the exact model that this goes with. There are probably some much more savvy computer people out there that know these models. (Please correct me if I'm wrong about the details)
There aren't a whole lot of these out here (I've seen one on ebay that is similar but without the dip switches and missing keys). I've put a reserve on it. I'd like to keep it but I'm moving so I can't take everything.
If you have any questions, please let me know.
