Honeywell's keyboard division became KeyTronic, so I expect this one to be similar to a KeyTronic. I doubt it's buckling-spring, I expect it to be rubber dome.

Keytronic existed long before Honeywell made keyboards =P

Honeywell bought Micro Switch, who used to make Hall Effect switch keyboards. That said, the above is most definitely a rubber dome keyboard.

There used to be some Univac/Sperry keyboards on eBay now and then with Honeywell/Micro Switch hall effect switches, don't see any at the moment.

In a Hall Effect keyboard, the depression of the key is detected using a magnetic sensor. This would be even more reliable than a capacitive keyboard. They're still made for scenarios were keyboard reliability is absolutely essential.

The Hall-effect keyboards I have seen have been fairly large.  They were also pretty old, so maybe they would not be so large if they were produced today.  I wonder if you could classify the Datahand as a (quasi) Hall-effect 'board.  I also wonder if anyone makes a regular form-factor, Hall-effect 'board.

If you looked for manufacturers of industrial computer peripherals I'm sure you'll find them. They will probably cost an arm and a leg and be linear.

I was searching for Hall-effect keyboards and found this beast (http://oldcalculatormuseum.com/sperryedc3.html).

Damn.  Rated for 30 billion operations.

Slightly OT, but is it possible to arrange the magnets and electromagnets in such a fashion that it could provide tactile feedback?

I'm pretty sure.  Webwit said that the Datahand has a slight tactile feel, and it uses magnet-based switches.

The Honeywell keyboard in question is, indeed, a rubber dome, because I am the lucky buyer.  Sorry if I outbid someone on this forum.  ;-)  

Date code is 9405, model nr. 101wn, catalog nr. 101wn63s-1e.  It has a DIN-AT connector, and, despite being a cheap arse rubber dome, feels quite nice to type on.  Let me know if you want further information.
