Reading Mark Jefford's posting yesterday jogged my memory.  The
Imhof from Blackpool Tower is indeed at the Birmingham Science Museum.
I restored it for them in about 1986.  The original barrel system had
been replaced with a roll player (unidentified) and the original weight
driven clockworks and pumping mechanisms were all removed and replaced
with an electrically driven crank and bellows system.

Early in 2000 we were approached by the science museum to dismantle the
ochestrion for it to go into storage as the museum was to be relocated.
As it turned out the task passed to someone else.

The Imhof currently in the Sanfilippo Collection originally came from
Melton Manor, Melton Constable, in Norfolk.  This was the film location
for "The Go-between" (Columbia Pictures).  It was purchased by Graham
Whitehead in the early 1980's -- much to the annoyance of many who knew
of its whereabouts but would not stump up the cash.  After restoration
it lived briefly at Ashorne Hall until it was purchased by Sanfilippo
in the early 1990's.

This instrument was as large in size as the Blackpool organ, with some
450 pipes and two magnificent brass weight-driven engines which, in
addition to driving the barrel, also operated the eight sets of feeders.
This is how the Blackpool organ would have been, judging from the
footprints left by the original system.  Unfortunately we never made any
recordings of either orchestrion, although I seem to remember there were
some available at the science museum.
