Do not forget that Roland also went funky on the number of keys on their Atelier Console Organs by Roland from their previous models to the current ones have the following:
Upper: 56 keys (C3 to G7) with 10 levels Initial Touch
Lower: 76 keys (E1 to G7) Waterfall type.

Last year I went to Las Vegas to make a recording at Phil Maloofs home, and all those huge Theater pipe organs anywhere from 2 and up to 7 manuals of 61 Keys each plus the pedals.

Most electronic organs had 2-3 variations,Console, Spinet and oversize Spinet.

The Console had 2 or 3 Keyboards 61 Keys(most of the time, except for now discontinued Yamaha Electones(and the top Kawai models) like the GX1, EX42, FX1, etc that had a third keyboard with smaller size keys and only 37, besides the Wersi, Bohm in their flagships that had 3 full size manuals. each board, And 25 bass pedals on the classical version 32 Pedals.

Small Spinets had 2 manuals of 44 keys each and 13 Bass pedals
Later the Oversize Spinet had 2 manuals of 49 Keys and 13 or up to 17 bass pedals.

Just my 2 cents.
