Clifton Precision Servo Specs

Hi,
I have a couple of DC permanent magnet brush servo motors I'm trying
to find the specifications for. They measure 2.25 inch diameter
by 4 inch long plus a 1 inch long encoder.

Clifton Precision (Litton)
Model No. DH-2250-AU-1
P/N 96214-994206-0001, Rev G.
Date Code 8244

I've looked at the specs on the Poly-Scientific site
at <http://www.polysci.com/datasheetlist.htm>
selecting: Permanent Magnet DC Motors
to download <http://www.polysci.com/Documents/moc23series.pdf>
or from <http://www.polysci.com/Motors/c23series.html>.

but these motors are not listed. They must have been made before
Northrop Grumman Poly-Scientific acquired Clifton Precision.

The encoder has a circuit board labeled "Texas Instruments" and has
a LM339N chip on it. Any idea if it is TTL compatible?

Any help would be appreciated.

Thanks,
