Central Scientific company DC Motor Demonstrator Antique No. 9 Educator Bipolar

Description

Central Scientific company DC Motor Demonstrator Antique No. 9 Educator Bipolar. I have had this a while but need to make some space. I have not tried to run this but the armature does have continuity when checked at the commutator. I don’t think the wire brushes are correct. I assume it may have had a phosphor bronze strip. Armature spins freely but it could use a drop of oil.
Let me know if you have any questions. I will pack carefully. Thanks for looking
