I suspect the geocities diagram tends to confirm that, judging by the Dover
Street substation location shown. The Piccadilly lifts can't have been
directly above the platform tunnels because they are under the road.

Yes, they were presumably on the northern side, as is the current
station.

Most maps show the station as south, but perhaps that's because it has
the most visible entrance? This one also purports to show the three sets
of platforms, and they look consistent with other diagrams:

/51.50673/-0.14206

I think they re-used the platform exists, stairs, and over-tunnel
passageway, but linked that to the new corridor to the south of the
running tunnels, rather than the 1906 lift landing to the north.

Yes, that's what happened, but *why*.

Incidentally I'm still coming up empty trying to find a picture of the
original (pre 1933) Dover Street station exterior. Presumably above the
"Dover Street Shaft".
