From the late 1930s and right up until 1970, Compton produced a range of electronic organs using the electrostatic system for both church and entertainment use.  The 'electrones' were found in a variety of venues including churches, chapels, crematoriums, holiday camps, social clubs and the home.  I have been told that the legendary organist George Thalben-Ball had one for home practice!  The electrones ranged from single manual instruments to large 4 manual specials.  

The following is of me playing a selection of models of Compton electrone:
