P 04 mag- Army marked or fake?

[D P McN]

Many years ago, I picked up a P 04/16 dated 1917. On the outside it looked really good, all the right markings (the wider flange on the main toggle pin), but the bore looked completely corroded, with non-extant rifling (which explains how I could afford it). A few rounds through it and some bronze brush work with Hoppes overnight, and I was pleasantly surprised that it had a good and somewhat bright, if worn and oxidized, bore. The magazine is shown in attached pictures. The serial number matches the pistol SN but no proof marks, Navy or otherwise, and in a small Army font and style as shown. Of note is the "two-tone" finish that seems to be nickel-plated front half, but stainless steel-appearing rear half. No other markings. The quality of the mag is excellent, but my guts, once I educated myself on these details, tell me it's a fake. I have seen published photos of Army Pioneer troops with P 04s on late Navy buckled holsters on their belts (I have the book but don't want to violate copyright, so no photo attached). The wishful thinker in me wants to believe it's a real Army marked mag, but I have no evidence to support this. Input, opinion, guidance and speculation all welcome!

Tough to give an opinion as the pics of the mag bottom are not clear. Body does look too new.

I suspect that scanning and posting photos from the book would fall under the "fair use" aspect of copyright protection. If you want to cross the t's and dot the i's, then cite the book title, author's name and page number, and you're covered.

Thanks to you both for your thoughts.
G2, please see a couple more pictures I took under a reading lamp that may be an improvement for diagnosis, but I suffer from cheap phone. I'm really curious about the "two tone" finish appearance of the mag. The rear half of the mag looks to me to be stainless steel (80% sure) while the front half is nickeled. I vaguely remember some all-stainless Luger mags were made by a firm called Haenel, but they were commercial and I believe were made in the inter-war period. All the WW1 mags I know of were all-nickeled.
Mr. Sweeney, I'm sure for all practical purposes you're right. The book with the picture of the Pioneers with P 04s is "The Navy Luger" by Joachim Gortz and John Walter. I think it's long out of print. At any rate, I'll need to dig it out and take a picture of that page and think it over.
