Information needed for Mannesmann Talley 57SHM-46BAB Steppers

I just acquired 4 Mannesmann Talley 57SHM-46BAB Steppers and recieved
limited information on them.
What I got was the following: 17.5 Ohm coil, 1.8 degrees step, 6 wire.
What I need is operating voltage, current and torque specs...

Any help would be appreciated, Thanks
