From Post 1912 & made in Suhl with Sauer & Sohn tubes in 8X58 1/2 Sauer. Not sure just how much Sauer contributed by the L are more than likely for Langenhan/Gebrüder Langguth/Luck mechanic and I am pretty sure the Eagle with the L on the left side of the lug is that of Luck. Luck & Sauer were very chumy @ one point. Right side scope mounts too.....

The scattergun tubes would be 65mm chambers.

Serbus,
