Do we have any knowledge regarding the stamped vs cast pulleys on the water pumps?  Did one predate the other, and when did the change take place?

I just looked in a WWII manual to see if those jeeps used a cast pulley but the pics aren't good enough for me to tell.  Sorry.
There's a reason it's called Ol' Unreliable

For a CJ2A, if there were ever a change to the pulley on the water pump, it is not apparent by looking at the part numbers in the 1945, 1947, 1949 parts manuals. They do not list the pulley separate from the pump.  The pump assembly number is the same in all parts manuals listed. (Part #639992)

This does not necessarily mean that they didn’t change the pulley.  There are other examples of Willys changing parts, but using the original number.

1- 1946 CJ2A   
2- 1949 CJ3A
