The clockwork barrel organ is part of an elaborate clock in the
Rothschild Collection at Waddesdon Manor. It was restored in 2006
by Stuart Dobbs for the National Trust. The clock and clockwork
were restored by Peter Watkinson of Chard, Somerset, and the case
was restored by Tankerdale Workshops of Sheet, Hampshire.
The case of the clock is made up of a lower pedestal, embellished
with French style carving and painted in a marble effect. Standing
on top of the pedestal is a carved wooden figure of Orpheus playing
a flute. Behind him is a large tree trunk, which has a serpent circling
around it up to the top. The gut line for the clockwork motor travels
up to the top of the trunk and over a lignum vitae pulley and back
down to a double line with the weight attached. On the hour the
clock sets the organ playing its tune. The organ part of the clock
is quite a simple but very well engineered device consisting of
the clockwork motor, bellows and feeders, windchest, pipes and barrels.

There is no sign of any manufacturers name on the organ but on the
bottom of the feeders in pencil is written Imhof & Muckle, London.
Imhof & Muckle were a German company who eventually built organs
in England but at a later date than this organ seems that they were
just the supplier in this case. During taking the leather from the
reservoir a pencilled name was discovered: Sorg 1869 inside the
leather and Henry Sorg London on the middle board. On the end of
each barrel there are inscriptions again in pencil about the tunes.
These are written in Dutch so it is thought the organ may be of
Dutch origin.
The windchest is laid
out with two wooden ranks on either side of the centre line, the
largest pipes in the middle, one being a Gedekt and the other
an Open Fluit. The Open Fluit also has an Octave Open Fluit, which
can be manually shut off using a slider. The notes of the organ
from the centre out are d – e 27 notes covering just over
two octaves chromatically. The windchest is constructed using
beech throughout and consists of a small well with 54 pallets
(Leather covered valves which when opened allow wind to the pipes).
One of the barrels has been restored, and plays movements of a
concerto, not yet identified. The other barrel will be difficult
to restore; it played an overture called Tancredi.
