Per Springfield Armory’s display a 1903 receiver took 125 operations, (upper band 38, trigger 19, bolt 77) if that helps anyone. Figure you have 30-40 milled parts in a Mauser at an average of 20-30 operations per part you’re looking at 1000 unique operations. Some factories might have had a dedicated mill for each operation, but some surely turned mills over to run multiple different ops. In that case you make a batch of one part, then change over to make the next. That’s how you end up with stock on hand after the war.
