Hi out there, I'm trying to get info on the two different types of motors used in the Lionel [2-4-2] "Baldwin Driver" prewar 229. I'm pretty sure one of them (the latest [40-42]) is a derivative of the prewar1662 motor which has a few other modifications. This "guess" aligns with the introduction dates of the 1662. The early version of the 229 motors, seem/could be a derivative of the 1681 motor. The prewar 204 [2-4-2] also has Baldwin Drivers and it seems to also be a derivative of the 1662 motor, but I cannot relate/cross-reference (parts wise) the 204 motor components to the later 229 motors using the references I have at hand. The ref I do have seems to indicate the "drivers" on the 204 and 229 are the same part numbers. Wondering if anyone could direct me to a source for more info. Thanks
