And too, don't forget in the mid 1800s that Sauer & Schilling were joined @ the hip:

I still remember something of Schillings being sold in 1914... I will continue to search.

Also, I have read that Germany passed a law that came into effect in 1924 that weapons had to be dated.... Going to chase that too.
