Martin, I wonder how close we can come to understanding the German/A and D relationship. Something that has always been a question in my mind is the wide use of the Greener safety and crossbolt on German guns. Some would say the practice was an avoidance of the A and D license cost. As we remember , Greener was sued by Deeley [WR] and the eventual outcome, after years, was that Greener was not guilty of patent infringement on the A and D 1875 [and later] patent. Does this relate in any way to the common use of the Greener crossbolt and safety in German guns ?
