Compton’s post-war organbuilding operations resumed in 1947. In that year, the Model 347 was introduced – a two-manual church specification, with 12 double-sided 5-inch discs housed in a detached generator cabinet. Electrones were then set to be produced in a number of standard models, with orders coming in for larger custom-built instruments, throughout the next two decades.

Further developments in generator design saw, in 1948, the introduction of the Model 348. This was based on 12 double-sided 2.5-inch discs, enabling the assembly to be housed in a smaller detached cabinet, standing no higher than the actual console. The 348 wave engravings were again something of a compromise, using the equivalent of pipe organ extension, with primes, diapason and harmonics being represented. Compton adopted a system of both three-digit model numbers and names. In the case of a model number, it is now reasonably clear that the year of development/introduction was reflected in the last two digits. Accordingly, 1952 saw the introduction of a further new generator system – probably the most familiar to devotees of the Electrone, with a single row of 12 double-sided discs housed in the console – the 352. And the organ which featured this new and compact arrangement? The Melotone.

Through the ensuing years, numerous new models were introduced. Not all were successful, particularly the smaller entertainment organs, which largely failed to compete with imported models from other manufacturers.

1951: Custom 3-manual for The Royal Festival Hall, London

1951: Custom 3-manual for The Free Trade Hall, Manchester

1951: Custom 3-manual for Rowton Castle, Shrewsbury (Royal Normal College for the Blind)

1953: Special Theatre Electrone for Ideal Home Exhibition, Kensington Olympia

1954: Model 354
A classically-voiced single-manual organ, featuring a Melodic Diapason from middle C, and Pedal Bass in the bottom two octaves.

1955: Model 355
A proposed Theatre Electrone for the Plaza Cinema, Caracas, Venezuela. Interesting specification, but order unrealised.

1957: Model 357CS
Basically a Melotone revoiced for church work. Noisy running of the generators was noticeable in a quiet church, and the metal casing was eventually exchanged for wood, in an attempt to dampen extraneous sound.

Model 357CP
Added thumb pistons and couplers.

Model 357CT
Baroque voicing. Later restyled as the Canzona

From around 1962, the 357 generator, was reduced to just seven octaves of primes, on a single-sided disc, relying on mixing for synthesis of diapasons, strings, reeds.
