luger machining?

[Vlim]

When Mauser restarted production in the 1970s they initially used forged parts that were machined afterwards. One of the parts suppliers (of the toggle parts) was IWK in Karlsruhe, formerly known as DWM. They developed a process that enabled them to cast several of the parts, which went in to production after trials proved they performed as well as their forged counterparts. the breech block was always machined from a forging, but the mid- and reartoggle parts were cast. Most of the small parts, which didn't have to withstand that much stress, were also cast.

The original pre-1947 production would have been done using a combination of forgings and pieces of square steel bar and round steel rod.
