Stepper Motor

Hi,
I am new to this group but have been reading the posts for a
while now. I have 2 questions I would like to ask about a stepper
motor I purchased on Ebay recently for $7.50 (a steal). The motor is
a Zebotronisc SM 87.3.18M7. The first problem I am having is figuring
out specifications of the motor. I have been to the site
www.zebotronics.de/ but my problem I hate to say is the metric
system. I can convert some of the data (I think) like Peak torque of
47.7 lb.-in. but the rest of the data is German to me. The other
question I have is the wiring connections for the bipolar parallel
Stepper motor, which is what this motor is.
If any one can help me understand this motor I would much
appreciate your help. Reguards.
