NWSL Stanton drive : corrected drawing

In the previous drawing, I made a small error : the 7 foot version of the NWSL Stanton drive is not symetrical, due to the modular construction of the truck for multiple wheelbases.

The most important change in the diagram is that the real centerpin has moved 0.87 mm to the (front) A end of the bogie. I consider as A ends those where the wires came out and where the removable coupler support is mounted (who is not shown in my diagram)

So you must deal with a "real" and a "virtual" centerpin with this motor bogie. The Stanton drive with 6'6" wheelbase would be symetrical.
