Thank you both for the information.
Are CG Haenel and Carl Gottlieb Hanel (I don't know how to put the .. over the a) the same person?
Any ideas on the RS in an oval?
To me, the CG Haenel/Carl Gottlieb Hanel makes sense on the CGH in the circle with the chicken.
The tops of the barrels are marked Gustaz Ratzel on the right tube and Berlin W8 on the left.
With the lack of the Berlin address for Gustav after WW1, and *H on the tubes, would it be reasonable to date the gun no later than 1920?
Thanks again for your time and knowledge.
