The original series included a "Concert" model - the Hammond D, which had additional pedal drawbars, that played higher notes. If I remember correctly, it also had a 32 note pedal board instead of 25 notes. Haven't seen one in years. Seems like there might have been a D2 also, but there was not a D3 - with percussion like a B3 or C3.
The computerized Native Instruments B4 synthesizer does have four drawbars for the pedal notes.
