The field info, yes. Armature I’m just guessing…

For an unusually high armature value, you can ohm between opposing segments on the commutator, or the brush wires, instead of the terminals. If you get a big drop in resistance between a pair of measurements then that narrows it down.

If you have low resistance but poor output then you need to clean up the commutator. The commutator and brushes wear down and that junk gets between the commutator segments and shorts them. Just be careful since there is insulation under the junk. You can use metal tools but it needs to be less like a flunkie scraping off corrosion and more like a dentist scraping off plaque. Instructions are in the manual too (probably). Once it’s loose grab some masking or packing tape and use that to get more of the dust out if needed. Use alcohol to clean up any adhesive residue from the commutator working surfaces.

You should also turn down the commutator using a lathe. Or any old car shop can do this for you for cheap. You just remove enough material to restore the commutator’s cylindricity.
