American Flyer 355 Baldwin mystery DC open-frame motors

They seem to be stock motors for the Baldwin switchers.

See here for an exploded view diagram showing this motor.

Thanks. but stock was an AC motor with an electrified field and either a four-position or two-position reverse unit depending on whether it was a 355 or 21801.  These are DC with a permanent magnet.  Granted, while similar in appearance in a diagram on paper, very different from each other in real live.  

they might be Kemtron slot car motors.

Thanks David D.  Kemtron and Pittman have a few votes so far, along with a couple for homemade and modified Flyer.

Here's another candidate:

The Ram motors had similar brush mounts, the top screws extended far enough to provide room for an extra mounting plate, and the "bulging" bearing holders appear similar the the ones on the Baldwin. I could only find a picture of the DC-850. Of course, as noted, others had similar designs. The Pittman 85 is very similar and (I'm pretty sure) uses some of the same parts.
