As Lugers were manufactured, there were major stopping points in the process where parts were inspected and improved by internal factory inspectors. This was usually done by observation and through the use of gauges.

The inspectors at DWM used markings that are different than you encounter with the people that worked at Mauser later. You can sometimes determine where a part or assembly was made by looking at these marks. The numeric digit dies are also different.

Toward the end of Mauser production, instead of using their own personal die to mark parts, a more generic "Werkes-Revision" intertwined WR die was used.
