I have maintained from B&W photos that the CCKW Military Senior oil filters as supplied from GM on a NEW CCKW were white.
Others have countered that they were, in fact, GRAY.
Well, here is an interesting tidbit that *might* back up the 'filters are GRAY theory:

There is one problem. The Military Senior and Junior filters are explicitly NOT discussed:
"During the war, vehicles supplied to the military used the military standard senior and junior type filters. For obvious reasons I'm going to cover units for civilian passenger cars and trucks only here. "
So while there is some creedence to the filters are GRAY theory, its not conclusive.
I will reserve judgment till I find definitive proof....
