In the works at the moment is the Walker organ from Sacred Heart Wimbledon. This is undergoing a full restoration, completing the interim work done in the 1980s. We agreed with the church that the pneumatic action should be retained, so we are having an interesting time dealing with that. Our impression is that we might have been the only organ builders who were prepared to retain and restore the pneumatic action. This even stretches to the original pneumatic pistons for which there is a remarkable bit of early 20th century organbuilder's engineering which needs restoration.
Rods and backs spring to mind by the description. What's so "interesting" about the action? When, historically, do you think organ builders used such complicated pneumatic mechanics not out of choice but because the technology to simply things hugely with electropneumatic actions wasn't yet mature? Would they have used such a complex action had they built it a mere twenty years later?
Could you have started again from scratch but with a completely differently designed pneumatic action? After all, the patents of Binns, Norman & Beard and the other pioneers of complex, successful and longlasting pneumatic actions have long since expired. Under what circumstances if ever would a seasoned builder ever consider building a large organ today brand new with a pneumatic action following the best of the historically proven designs, as opposed to mechanical or EP?

Finally, we are currently part of the way through a new organ for a church in Lagos, Nigeria. This is a three manual instruent instrument of 41 stops.
Nice to hear of more organs coming my way (though sadly I'm a few thousand miles from Lagos!) I hope they have a team of enthusiasts willing to learn and play, like here in Kenya or Uganda. Just make sure you pick a hotel with powerful airconditioning when you stay in Lagos! How does the climate (and the ubiquitous termites!) affect your choice of materials for somewhere tropical?
