From the works of Kent, Sharpe and others, all agree that the average German case “Lot” was 180,00 cases, based on the life of the tooling (draw dies,bunters, etc.) This applied to 7,9mm cases, whether brass, plated or Lacquered steel. 9mm Pistol case Lots usually ran to about 230,000.
The 7,9x33 Lots were the same as for Rifle (ie, 180,000).
New dies gave a different “case” and anyway, a 180K lot was a manageable number.
Loading Lots , again,(for ball) usually matched Case Lots in size, but the special loads could have have been as low as 60 K of cartridges.
Loading Lot sizes depended on Powder Lot size; with Primers, these were made in “Millions” because die design was much simpler, and wore down less.
Can you imagine withdrawing a lot of 1 million cartridges because of a fault in a few??
Components were continuosly monitored, before assembly. The the finished cartridges were given the once over, before being released for “use”
