Greetings, it's me again. You guys do such a great job on providing information which would otherwise require years of research or a vast library that I just can't help but turn here first. Thank you for all your previous assistance in my prior queries. I have a Kommer .25 acp vest pocket pistol, no external serial number. It has above and to the rear of the trigger, stamped, D.R.P. ANG., and has a crown over "N" "proof" marks, I assume German. On the inside of the right frame, bottom grip, is a "B." No markings on the mag. Can anyone tell me what years these were made? Any other info would also be most appreciated. Thank you for you interest in this matter.
