Originally installed in March, 1933 for the opening of the Gaumont Palace (later re-named the Odeon Theatre) in Cheltenham, Gloucestershire, UK, the organ had 602 pipes in eight ranks; namely Diapason, Tibia Clausa, Stopped flute, Violin, violin Celeste, Krummet, Vox Humana and Tuba. Thus, in the parlance of theatre organists, it was a 3C/8 meaning it had three manuals (the top one being a coupler) with eight pipe ranks. In addition, four sets of tonal percussions were provided; namely Vibraphone, Glockenspeil, Xylophone and Chimes, plus the usual set of drums, Cymbals and other special effects.

The opening performance on the organ was played by the acclaimed theatre organist of the day, Frederick Bayco. It remained in continuous use in the theatre until 1968 when it was removed for shipping to Australia. Surprisingly, the Cheltenham organ was the first Compton theatre pipe organ to be "exported" from the UK. It was bought by a commercial concern which owned the Dendy Theatre in Brighton, Melbourne.

The Dendy already had a theatre pipe organ, a WurliTzer (Ex Capitol Theatre, Melbourne), owned by the Victorian Division of TOSA and this was proving to be very popular. The Compton was then earmarked for installation in a restaurant planned as part of a redevelopment of the Dendy site. A change in plans caused the Compton to be offered for sale in 1977 and a Canberra consortium successfully negotiated the purchase. Shortly after it was offered to TOSA ACT and in October 1988 the Compton fell into the enthusiastic hands on the TOSA restoration team.

The poor condition of the organ presented the restoration team with a daunting task but after thousands of man hours spent releathering, rewiring, mending, manufacturing, modifying and repainting and over $40,000 expenditure, the organ was heard for the first time in its new home on Thursday, 7th November 1985. The inaugural concert on 17th August 1986 was performed by Tony Fenelon, a well renowned Melbourne Theatre Organist and TOSA A.C.T.'s patron.

The restoration work did not stop there, the solo manual and the accompaniment second touch were not operational at the time of inauguration but these have now been completed by the team. Operation of the organ, both its original installation and the Canberra installation has taken its toll on the old switching stacks. Arcing of the electrical contacts has resulted in erosion and deterioration so replacement and upgrading using the latest technology will result in enhancing the organ's musical specification and, hopefully attract a wider cross section of the community, particularly the younger generation who, we hope, will experience the thrill of Theatre Organ.
