Bulgarian Mystery

If the pistol is a rust blue wouldnâ??t it have some white on the interior. To me this seems to be a salt blue where the whole pistol is blued (inside and out) which would put it in the rework category around the WW2 period (or possible later). I am not too knowledgeable in the luger area so correct me if I am wrong (I am more a P.38 kind of guy). It would be nice to see some pictures of the pistol; itâ??s always nice to see something new. Thanks to herb to bringing along an interesting subject. Jr
