I believe Slonus found this tid-bit of info which is very insightful as to the sourcing, especially Sauer:



from http://www.jagdwaffensammler.de/index.php?id=12

And apparently circa WWI Max Gründig and Hugo Gründig were the owners. It is here that I am most curious if the guild allowed a widow and sons to continue marketing with titles such as Hofbüchsenmacher, etc.

Kind Regards,
