The "B" is in the appropriate position under the serial number. I agree that the "halo" is not the result of stamping but may be from wear or contact with something that removed the blue. I still am not totally comfortable with the slant of the "B" but am willing to accept it at face value. It appears to be a legitimate rare Luger and the condition attests to the hardships of ranch life. I am perplexed by the presence of the "B" suffix since this is obviously one of the elusive 7" Commercial pushbutton stock Lugers, but there is an awful lot about early Lugers that I freely admit I do not know. Maybe if I live another 50 years I will be a little better informed
