But the Victorians didn't have escalators, so why would there have
been a passageway in that particular location? Its parallel and next
to the passage between the bakerloo line and the northbound northern
line platforms, so it doesn't seem to be purposeful.

Don't forget that most deep stations had lifts in the beginning.
Staircases were converted to escalator machine chambers also.

A lift is possible, but where would it have gone? The passage is
directly beneath the westbound platform of the circle/district, and a
lift shaft there would have to have cut through the platforms, making
them rather awkward. Now there clearly used to be a lift of some sort
on the northern side, as the escalator on the northern side from the
under-circle-line passages to the ticket hall passes through a space
that is clearly circular, and cut-through lift-shaft like. But I can't
fathom where the lift could have gone to, since there doesn't appear
to be any passage on the northern side of the northern-bakerloo link.

Its more like it goes somewhere that could then go to a lift perhaps.
Perhaps it linked up with the other side of the spiral staircase?

That spiral staircase is a bit of a curiosity really - why is it
situated so far to the south of the passage linking bakerloo to
northern line, but only go high enough to emerge beneath the circle
line platforms; if it was intended to only go that high, it would have
been better to put it next to the linking passage, if it was set so
far south for the purpose of reaching the surface, why doesn't it.
