Question on early vs late 1937 Lugers

[Frank]

Bob, I agree with Jim. There is another variant, which is found from about the mid-S Block into the T Block. This variant has the strawed parts of the early 1937, but has the Mauser Hump from the late 1937 Lugers. This variant would add another 5 to 10 percent above the early 1937 Lugers, all else being equal.
