I can't find a model number on the organ but can describe it to you.
It has two keyboards - the lower one has a series of switches to the right of it, being tremolo, light vibrato, full vibrato, vibra harp, string and short sustain. The on off switch is at the far right on this keyboard.
To the left of the lower keyboard the switches read, brass, drum, cymbol and clave pedals, snare drum acc, brush acc, woodblock acc.
The top keyboard has to the left of it two rows of switches. The top one has tibia 16, clarinet 16, tibia 8, salicional 8 saxaphone 8, oboe 8, tibia 4, solo reed string accent and solo-perc re-it.
The row of switches beneath that reads , flute 8, string bass 9, pedal sustain, loud and soft pedal, horn diap,8, flute 8, gemshorn 8, orch flute,4 and loud and soft volume.
Does this help?
Success - inside we have found the following information.
It is a Baldwin Orga - Sonic, model number 91R.
Supplied by D H Balwin Company, Cincinnati, Ohio.
I imagine it is fairly old but in good order.
Hope this may help you find me some kind of suitable operating manual.
