AMI? Rockola turntable motor-part # 233579-4-A

Hi,
Turntable motor part in hand. Looks like Rock-ola turntable motor, but
has triangular metal plat above motor, attached to motor housing by
three bolts. One black rubber grommet in one of three mounting holes on
one of the three corners of mounting plate.
Also has two brass "feed in" oil tubes (similar to Seeburgs), one at
top of motor and one at bottom of motor. Has a very SHORT shaft coming
out top of motor (less than a half inch) with no ridge on top for a "c"
clip to attach a rubber idler wheel.
The connecter is a three pin (center pin missing) that resembles a
Rockola connecter to a sixties junction box beneath the turntable; but
it is "spliced in" to the two wires. The white lettering stamped onto
it reads "75V-60c", and the apparent part # reads 233579-4-A If the
motor is rotated one more quarter turn, the white lettering says
"GI40440", with the numbers underneath reading "190-6506.
My question to anyone familiar is, what do I have here? I figure it's a
turntable motor, but am not sure if it's originally from an AMI with a
connector spliced in to adapt to a rock-ola? Or what? The triangular
mounting plate above the motor is not consistent with rock-ola
turntable motors I've worked on before. Could it even be from a
Wurlitzer of the 50s, 60s, or 70s? Does any one have access to the part
#s to cross-check the # on my motor against to see what indeed this
motor goes to? Thanks in advance, Rob
