What brand and model number are these organs? 

Virtually none, if any of the electronic organs used a CV compatible
architecture for their main pitch sources. Instead of varying an
oscillator's pitch to get different notes, they either had separate fixed
oscillators for each pitch, or they had master oscillators with divider
circuits to get the lower pitches.

There were however a few organs that incorporated an analog synthesizer as
a third keyboard, often a smaller keyboard at that. It might be possible to
arrange CV input or output for this type of keyboard, if your organ is so
equipped. I have no idea if these systems were typically V/Oct or V/Hz.
Does anyone else know offhand?

Hmm...  I wonder if cannibalizing an old junk organ would be a way toward a
cheap D.I.Y. mono synth?
