1) Any idea of age? s/n is 27434. I'm leaning toward 1906 as that
seems to be when the no. 3 showed up, and by October of that year
there had been some 40,000 of them built - but that's assuming that
the serial numbers don't carry across all models. I'm surprised if
they built that many of them before they were rendered obsolete by
a newer model, though.
2) The lack of '2' key is really the main thing stopping me from
bringing this thing home. I expect they're common to many early
Burroughs machines; is anyone known to carry parts from junk
machines, or has anyone succeeded in creating a reproduction key
using modern materials?
Looks like you're age estimate is pretty good. According to the
following site, that serial # would be 1904 - 1906:

On the home page they ask "Need a key?", but it turns out they mean
the key to open the case.
Probably worth asking at sites like that though.
I was working on a few mechanical machines recently and someday I
have to rebuild a couple of them, but I'm no expert on mech calcs.
On the page you listed, they mentioned the "oil-filled dash-pot". I
had to open one of these (hydraulic damper) to rebuild it a couple of
weeks ago - what remained of the 70-odd-year-old oil was pretty vile.
