Anyone have Electrocraft motor specs for models E670 or E530?

Does anyone have the specs for Electrocraft Model E670 or E530? The
E670 reads about 5 ohms from brush to brush while the E530 reads
about 2.2 ohms. I would like to use them to drive a cast x-y table
with timing belt reduction but I am unsure of how suitable they might
be.
