If you're interested in this, watch this [1] very in-depth 1943 movie called "Crystals go to War" which documents crystal oscillator manufacturing step by step. Honestly, I was amazed by this. I tend to think of technology as pretty primitive in the 40s but this is a great reminder of how sophisticated technology could be even back then.

You might be interested in this documentary from 1943, which shows the manufacture of quartz timing crystals from start to finish. The amount of skilled labour required to produce a single finished crystal was utterly staggering and highlights just how essential radio communication was to the war effort.
