Input on this Unknown Off Brand Welcomed

[Granby]

That is a great observation and now that I have visited the machines in person, again today, I am in agreement that the "Granby Console" motor board and the motor board in the "mystery cabinet" are extremely similar.... needle cup locations, volume control, even the mounting screw locations....

Now, I need to dig into some period advertising and see if I can document this cabinet - even if by a different maker.

All part of the fun!
