old step motor connections

hello there

i got an old stepmotor (astrosyn miniangle strepper type 23lm-s261-g1).

there are 6 wires going out of the motor and i dont know which is which. since there are six wires i guess this one is a unipolar motor.
the six wires got these colors:
-black
-red
-green
-white/red
-white/green
-white

any suggestions how i could find out? i got a multimeter.

thanx

Measure the resistance between each pair of the 6 wires - then look up 6-wire stepper motor wiring diagram and relate your data to this. There will be two groups of three each of which is a centre-tapped winding.
