My first and appears the rarest
 

1906 French Mark Commercial as discussed on page 106 Luger at Random. #51872. In the 8 years Ive owned it, Ive never seen another. A version purportedly appears on another site that was 9mm and could never been veryfied. It was very suspect. Im trying to research this luger and have had no luck. I post this every couple of years to figure out La Petite mal au cue! tks Eric
