I should give my P.1 another look, as I don't recall observing any Crossed out or X'd out stamps / markings. However, we must remember that my example is not the same as some of the other pistols, as it was manufactured, or at least assembled by Manhurin in France expressly for issue to, & use by the W. Berlin Police Force, as the way I understand it, they were allowed any German produced weapons, due to Treaty restrictions put it place intially by the Allies during the Post War era. In fact, I picked mine out of about 20 boxed examples, specifically for it having documentable Police lineage. I almost chose a very early, 1956 IIRC P.38 that day, but just couldn't pass up a Berlin marked piece. A few years later I met a former member of the Post War Berlin Police & he gave me a beautiful Thank along with a few other items for my collection. He also definitively confirmed the photos of my Manhurin P.1 as being the exact pistol he previously carried on duty. I still remember his name, Werner Schulde, & he used to sell on eBay years ago.
Now, In reference to the overall import logistics of the Interarms haul, I totally agree with you as to that particular sequence of events. Without a doubt, the red, IA Boxes were produced domestically here, although I do harbor some suspicions regarding exactly how the accompanying pistol magazines were shipped over here, as I've observed many pistols exhibiting not # matched, but 'date matched' magazines with their pistols. Yes, they may have separated spare magazines by their dates, & then upon their final, pre sales packaging were matched by date to the respective pistol ? Yet, that particular method surely doesn't appear to be an efficient way to accomplish that task ? The magazines may have been shipped over here with the guns, as although creating a heavier shipping weight, it did alleviate the task being performed over here ?
And, you are indeed correct about the 'BMI' mkg. I however never attributed it to use on the local, Lander Police issues, only on the BGS issued pieces. ( Although somewhat off topic, I have a nice 1965 dated, 'Rhineland Pfalz' marked Walter PP, which doesn't exhibit any BMI mkgs. Markings are: 'RP' within Circle, definitely Factory applied prior to bluing. I also came with it's Holster & black plastic Walther #'d Box / Case. )
I truly look forward to sharing all my odds & ends here, via photographs of course. Every day as I dig deeper, I'm coming across assorted Holsters, etc. So, please stay tuned as they say ! THANKS AGAIN for your very kind assistance.
