Motor of the Week - Week 5 - Please help identify!

It is a Marx motor for sure>>>
Marty

This is another post war Marx motor, powering the sheet metal locos like Commodore Vanderbilt, long sheet metal loco, but NOT the Canadian Pacific types, nor the 999 or 666, or 1666.

Whomever told you the whole batch was for Lionel locos was really full of BS.

Thanks, Roy!   Yup, the vendor online piled shovel loads.

Thanks Marty! There are a few junk Marx motors in the box.

Can you give a motor number for this one?

Regards,

Pete

Good morning, Brothers! Hope you had a great Independence Day!

Before awarding the C of A we need a bit more precision on the motor identification. Can you add a catalog/part # or narrow down its production time/use?

Best regards,

Pete

From Greenbergs vol 2. A great resource 

That's good enough for me.

Frank confirmed and documented with model designation Roy's initial assessment. So this week, a Certificate of Awesomeness goes to franktrain

and to ROYBOY. Since this is Roy's second C of A, his Certificate comes with an oak leaf cluster.

Congratulations, Brothers!

I did some digging online too and found some photos of Marx motors. Comparing them to the motor at issue I was able to eliminate the 400, 490, 655, and 895 in addition to those mentioned by Roy. The C motor and distinctive brush plate used here looked identical from the port side to the 494, 451, and 3000 , but I couldn't see the gearing from the starboard side so couldn't definitively determine the model.
