Apologies for even fewer updates over a longer period of time! Other people have started their own sites about this organ and its restoration. Links are provided below:
The organ was moved to Rochford in 1972, but was not fully operational until 1984. The colour photos came from the website of the National Pipe Organ Register in Cambridge. The black and white ones were taken by John Sharp on 11th November 1984
The organ is now in the late stages of reinstallation in a barn on the outskirts of Southend. All photos in this section were taken by me with an APS camera.
It is now being re-installed in an 18th Century barn (build in 1770 - the year Ludwig van Beethoven was born) by Gerald Usher, a part time teacher at Southend High School for Boys.
The organ has 500 pipes, lots of percussion and special effects. It is powered by a 15 horse power motor and a 3ft fan. The console case is of the "Rainbow" type, and is like the one at the something in Grantham. It would probably originally have been on an electric lift, but is currently sitting on breeze blocks... :-) Apparently, some organs were on hydraulic lifts, but these tended to leak leaving the organist to sink back into the pit before the end of his interlude!
The mechanism is electro-pneumatic with 22,000 interconnections, running on 15 volts DC, powered by the original Compton generator.
