The two wind reservoirs were completely dismantled and restored with new leather. Two reservoirs are not necessary on a blower-fed organ, but as they are original I retained them for historical reasons.
The original feeders had been removed when a blower was first installed, but the leather valves are still in place. I glued these down to prevent leakage. and renewed the transfer manifold leather and cleaned out the filter, The spill valve was re-leathered, and all springs, hooks and eyes were treated with black Hammerite.
The blower was re-installed at this stage, so it could be used for blowing out dust and checking as progress is made on chests and pipes.
