Carol and Jerry,

It was good to include the electrical specs, but
we need the physical size of the motor as well.

That, more than anything else; is your best guide
to estimating torque. The same size motor can
be made with an infinite variety of windings;
all of which produce about the same holding-torque;
but differ in driver-requirements, speed capability,
etc..

I doubt that part number means anything. It's almost
certainly an OEM part number; for IBM or whoever.

If it's a typical "IBM printer stepper", it's a
single-stack size-34, with a funky shaft-size <g>,
and a 2-deg step angle. I.e., 180 steps/rev instead
of the more common 200/rev.

And if that's what it is, then it's about 125 oz-in,
give or take 20%.

Hope this helps a bit,

Richard
