Between this old thread (650 case feeder electric motor replacement)over on Brian Enos site and the info you gave, this is probably the gear-reduction motor they use.

Now to just figure out what the motor alone is.
What does the other side of the gearbox look like?
That looks like the same one I paid $8.50 for on e bay a few months ago!
GD,
Can you offer a little help to the seller on eBay that you got the geared motor from?
Was it new or used?
