This is a very early Trinity motor based on the Igarashi teardown. As the can is not of the usual metal surface but got a red painting, we think it might be not a basic stock motor but a machine modified version. Those Machine Modified motors usually got a hotter winding of 32 Turns where the basic stock motors were 35 Turns. Also the armature was epoxied and balanced and the magnets had been zapped. The main difference to the full modified motors were machine wound instead of hand wound also bearings were missing.
