Comments:

GE Tri-clad motors were introduced in 1940; The last patent listed on the tag is for the centrifugal switch, granted in 1942.
I purchased the motor from an estate sale.
Cleaned up and repainted, the open bearings were in good shape, only needed cleaning and repacking with fresh grease.
The capacitors are in the end bell; Two Vanguard 324-389 microFD.

Excerpt from "New Tri-Clad Motor Introduced" (Chem. Eng. News, 1940, 18 (23), p 1102.):

"CHANGING requirements of industry have resulted in introduction by the General Electric Co., Schenectady, N. Y., of an entire line of completely new polyphase induction motors in integral horsepower sizes. Known as the Tri-Clad motor and representing one of the most extensive product changes in the company's history, this general purpose motor has called for new methods in manufacturing and introduces many protective features.

In all ratings the new motor presents modern streamlined appearance, more complete protection through use of a cast-iron frame, major advances in insulation of current-carrying parts, and improved bearing design and lubricating arrangements. It incorporates the cast-aluminum rotor and a pressure-relief system of greasing for ball-bearing motors.

A cast-iron frame of the box type is used instead of the conventional open frame. End shields, designed to match the frame, are enclosed above the center line. This combination minimizes contact of vital motor parts with foreign material such as lubricants, coolants, other ... "
