Discretionary Blueing

Although not soaked, rust blue like Luger must contain a step to clean up the interior after bluing. This was mass produced, made in industrial way -- from what I saw on original Wartime C96 samples, the oxidation liquid must be sprayed onto the surface. During wartime, they did not blue inside (unlike earlier ones), they did not clean up the interior after bluing, and left a unique interior "blow-like" bluing pattern inside the frame. For Luger, I would assume they applied similar machinery (probably a sprayer like device) doing that like Mauser, but they clean up the interior afterwards.
