C.P. Goerz Berlin 4x is an interesting WWI scope because it was mounted on a mount which could be seen as the ancester of the WWII turret mount. This was, with the similar Goerz 3x mount, the only mounts from 14-18 that could be changed from a G98 to another one without modification (having the right bases on it, of course).
WW1 sniper scope made by R. Fuess Berlin-Steglitz. This 5x model is pretty rare, compared to the Fuess 3x scopes. Green paint was pretty uncommon 14-18 sniper scopes. Only a few manufacturers used it on their scopes, mostly late war.
World War I sniper scope made by Hensoldt in Wetzlar. This model, Ziel Dialyt 2,75x, probably was the smaller sniper scope used during the WWI. This one was mounted on the rifle (Gewehr) N° 7835. This precise scope was reblued after-war.

Pre WWI G.Z.IIII Prismatic scope or “Teleweit” made by Carl Zeiss in Jena. This sight was one of the very first telescopic sights made by Zeiss in the early 1900’s. These scopes, going from the model GZ I to GZ IV, were the ancestors of the high quality sniper scopes used in later wars.
Luxor 3x sniper scope made by Oigee manufactuer in Berlin. This model was one of the most used during WWI. Its deported mount is also typical. This one bears the same rifle number “n° 712 i” than the scope main tube. Meter dial is Prussian 1-10 style.
C.P. Goerz Berlin 3x scope wearing the rifle number (gewehr. Nr.) 6876. Meter dial is Prussian style 1-10. This mount was one of the first interchangeable models made for sniper use, allowing to mount the scope on any other rifle fitted with the same bases without needing of gunsmith modifications. It can be considered like the earliest stage of the later turret mounts, used during WWII.
