JGA was used by Julius Gottfried Anschutz of Zella Mehlis. Many times it was encircled. They were prime contractors for military rifles & flare pistols. It could be construed that the bird is a Chicken form on military weapons but other makers used a similar Prussian Crowned Chicken/Eagle as a process mark. The crown on others may have been removed during the RWE period.
