I got hold of this old FARFISA Parter 5250R last week for 85 pounds! It has some brilliant sounds on it. Mixing the main ‘Flutes’ section with the MONO section can create some classic organ tones. Using the vibrato and reverb you can really fill out the sounds as well. It even has an octave of bass notes as foot pedals and an automatic drum section compleate with ‘fancy chords’. BRILLIANT!
Here is a video of me improvising on the organ after a few hours of playing it.
