My understanding in the difference in C11Q-1193-A,B, C, D, etc and C21Q-1193A is that the 1941 pattern used several different spacers in different sizes to suit, while 1942 used only one spacer of a standard size, but built that up with different shims.
I suppose someone thought that keeping supplies of multiple sized spacers was more of a production or logistical supply problem than having only one spacer and supplying shims for adjustment.
