That "interesting wooden base" is clearly not the original host for this machine. The hinges on this 66 (9 5/8") do not match the hinge inletting on the base (9 3/8"), and someone who should never have been allowed to touch a saw enlarged the opening in the base by about 1/2 inch on each end to about 15 inches. Also, for some unknown reason they also very roughly cut away the ledges on the front and back that the machine is supposed to sit on. Who knows what used to reside there.
The machine does have a motor attached, but there is no sign that there has ever been a three-pin connector on it. In fact, there is no wiring at all, from the motor or the lamp. And, the storage compartment is just an empty space with no sign that it has ever held a controller or a pedal.
Up until I bought the 66-6 I'm working on now, I had just considered my wife's machine as a decoration. It has now been offered to me as a parts-donor if needed.
