EJM,

I do not think the Nazis had "work stoppages" from what I have read of their tenure in Germany. And, this is well before serious bombing would have disrupted factories or supplies.

That said, every manufacturer used subcontractors. The big guys, like Eickhorn, did quite a bit in-house, while the small guys were more assembler than manufacturers.

Ryan,

You are right. Anomalies and questions everywhere. The least of which is why they used that rat squirrel.
