I was logging some German WWII boxes into my collection, when I realized that I already had an example of an emp 1941 Lot 41 box, but apparently I had logged it as using CWS case lot 4 of 1941 when the box I was logging was lot 3. So, I dug out the previous box and sure enough, in production lot 41, emp had used cases from both lot 3 and lot 4 of 1941. This is just one of a number of cases I have seen where there were variations within production (Load) lots using different primer lots usually, but occasionally other components. Some factories just state on the label that they are using various case lots, but here they printed different labels. Amazing detail in the record keeping.
Both of these boxes had triangle labels stating that the ammo was for training only, probably because it was CWS case I suspect. Does anyone have documentation that CWS case 9mm was to be used only for training???
