Opus 12 (1990)
2m + P, 24 stops. St Mary's Collegiate Church, Haddington, East Lothian. Delivery was deferred because the design concept was considerably enlarged from 17 to 24 stops to include pedal towers with 16' Facade Principal pipes of 70% tin. This instrument is extensively used for concerts and recitals, notably in the Lamp of Lothian concert series. Consultant: Prof. Peter Williams. A recording of organ music played by Dr John Kitchen (Edinburgh University) has been made on cassette and is available from Lammermuir Pipe Organs.
