I would vote that there is a pretty wide range of bluing finishes on the WW2 guns, some with purple parts, some not, some with a very dark blue, and some lighter. And I'm not certain if it is a matter of wear, or cooking time, or how "used" the salts were, etc.
More pictures would help, but I'm not scared, yet.
But, do I see a strawed extractor?
