I got a '46 OS 1.5ton with a 216 that came with the crank.

A= 5 9/16"
B= 7 13/16"
C= 27 4/8"
D= added by mistake smile
E= 7/16" end to center of pin

Bar stock is 11/16" diameter

Pin is 5/16" diameter, and they stand 1/4" tall

The end of crank looks it has a forged/cast section that is added to the solid bar, or forged somehow onto the end. The pins do not go all the way through the middle of the bar, so they may be more accurately described as nubs. The hole at the end is 3/8" deep and 7/16" diameter, and on mine is not perfectly centered. It may be a result of forging the end of the rod to form the pins. if you want a close up of the end let me know.
