Measuring armature resistance through the brushes is VERY tricky. I'd try
spinning it at 1000 RPM and measure the voltage. (If you have another
speed easily available, like from a lathe chuck, use that and correct for
the different speed.) This is a MUCH more reliable reading than the
resistance
with the brushes.

If your reading is correct, then your above supposition is probably
pretty close.
