Not Lugers, but Mauro and Gerben's book contains pictures from the Mauser Oberndorf C-96 production line. I doubt there were a great number of changes to production techniques through production fo the Luger.

The work was done in batches, drawing from finished parts stocks sourced from other lines or stocks from prior operations.

Of great interest is a set of books on the Nickle M1910 and M1914 pocket pistols in the Mauser archive. These books document the workers that were fabricating parts as well as the time and cost involved for each part. Of particular interest, we see Mauser's master gunsmiths including Nickle also worked on the production line to makes parts for the pistols.

You'll find limited documentation of the production steps for Lugers at Mauser during WW-II in Jon Speed's book on Mauser Pistols. See the process sequence document on page 227.
