Odd BBLs From Numrich

[m1903a3]

Since I have plenty of Navy lugers I measured a half dozen of my P.04s and came up with a 15mm diameter of the base band and 19.5mm from the bottom of the band to the top of the flat. Subtracting half the diameter (7.5) that makes it 12mm from centerline to the top of the flat. I measured my only lP08 and got the same result, which matches the lP08 drawing.

Putting my P.04s nose to nose with the lP08 confirms they have the same base height for the front sight.

Now for the interesting part: I have two P.08s. One is a mint 1918 Army P.08 and the other one is a rare Navy contract P.08 from the Navy's 1913 contract for 150 P.08 from DWM.

Both P.08s have the same 15mm band diameter as my lP08 and P.04s. However, they both are 17mm from the bottom of the band to the top of the flat. That translates to 9.5mm from the center to the top of the flat, not 10mm as shown on the print!!
