The Lady Isabella was a pumping engine. It was designed to clear water from
the greatest depths envisioned by the owners at the time of installation,
which is why it has space for a second counterweight box that was never
fitted. I have a book bought on the Isle of Man years ago, based on a
research thesis, that suggests it was a very unusual system they used, with
the pumping stroke on the descent rather than the lift stroke.
