Raimey, Thanks for the ID of grade. Do you know where I might obtain a catalog or reprint of Sauer’s offerings available in Germany when this gun was built(1911)? Obviously, there were different models available in Germany then as opposed to their export models ( Grade 45,60,etc.) in the 1907 catalog, they mention that they are prepared to make doubles up to $1000 U.S. I assume that would be a bar action sidelock model. Thanks, Sandlapper
