I will try to post a pic later… I purchased an early (48’) 2333 F3 locomotive in need of some parts. Although the engine is clean it appears to have been pillaged for parts at some point. Now the question. This engine has the early horizontal drive motors with the fiberboard, NOT BAKELITE) brushplates. These motors are 1948 issue only. On this motor there is a rivet which secures the field to the aluminum pinion housing. On the brushplate side of this rivet is a threaded collar which accepts the screw which secures the brusplate assembly. For some reason escaping me, this piece is missing in action. Do any of you know the part number, and where i could obtain a replacement? This part does not appear to be interchangeable with the later bakelite style brusplate assembly. They are not reusable.
That part was never sold separately it was a component of the 2333-M1 motor.
The screw that mounts the fiber brush plate to the motor is a 6-32 X 3/16. Depending on what you have left, you may need to fabricate the entire part or modify a PC board stand off available from various electronic suppliers.
If not finding the original part is not a show-stopper, you could just bolt the brush plate on with long 6-32 machine screw, with a spacer between the brush-plate bracket and the field. Except for the nut, it could look exactly like the original. In fact, you could use the screw as a rivet if you want.

Thanks again for everyone’s help. Called Jeff. He is very knowledgeable. Turns out the stud is known as 2333m-mfs for motor field stud. He told me a replacement was made at one time, but is no longer available. I bought a whole field assemble so soon the ole’ gal will be rolling again.
