Vending motor

I have a Westinghouse WC-102 that is missing the vending motor.  After talking to Steve at Fun-tronics, I found out that the motors are not re-produced by anyone.  He suggested trying Graingers for a replacement motor.  Does anyone know what RPM that motor should run at?  I'm thinking around 20 RPM which creates a complete vending cycle ever 3 seconds.  Or does anyone know a source for a replacement motor?

If what I remember is accurate, the electric-motor should unbolt from the gear reduction part of the vending motor
is it an open frame motor? (you can see the part that spins in the middle of the frame/electric coil assy. got a picture? that whould help ( of the front, side, & rear view of the vend motor) '>
