Bridgeport Boss 6 Stepper Motors

Does anyone know what the model number of the stepper motor that was
used on the Series I Bridgeport with Boss 6 control? The ones from my
machine are already gone. I know they were made by Superior Electric,
but nobody at Bridgeport or Superior knows what was used.

I would like to find the specs so I can get a better idea of the
force that Bridgeport provided on each axis. This will help me in
sizing some new servo motors.

Thanks to everyone who responded to my previous encoder count
question.

Best Regards,
