Addition of 32ft Pedal reed extension.

The Pedal Ophicleide 16ft was extended by the addition of 12 pipes, the new extension will be known as Double Ophicleide 32ft .  The new chest was winded from the same supply as the Ophicleide.  An additional stop position was added at the bottom of the Pedal jamb, the Double Ophicleide drawstop being installed below the Ophicleide, and all other stops moved down one space; a reversible foot piston for this stop was provided.  The keyboards were dismantled, fitted with new regulating buttons and re-set.  The drawstop actions leatherwork was checked and renewed as required.
