Pittman DC-196 hybrid motors
During the Pittman Era, the practice of de-winding and re-winding slot car armatures to improve their performance was still fairly uncommon. Instead, builders swapped armatures between motor setups in an attempt to get an edge on the competition.
Swapping a much hotter Pittman DC-65X armature into a Pittman DC-196 or 196A setup improved its performance significantly.

And in another post: The dc65x motors were rated at 6v. The dc65 rated at 12v. The x was a much hotter wind. When I talked to Charlie PittmanI told him we needed hotter winds. The 65x arm in the 196b really flew and I raced against many a rewound can with it. They ran forever also. I really can't remember anyone rewinding the 5 pole armatures.

The DC-196B motor would also have been a prime candidate for such parts swapping, except that it was introduced at a time when the top builders and drivers were moving on to the Mabuchi tin-can motors.
