Holster Identification and/or Info

[Geladen]

Hello All,

I'm a relatively new member to the forum. I recently made my first post over in the P.08 forum. I'm hoping the knowledgeable people here will be able to help identify a holster and extra magazine that came with a byf 41 Luger I recently acquired.

I have attached some pictures for reference. From the limited research I've done, I think it may have been a WW1 Imperial Navy holster that was reworked for use in WW2. I've included pictures of all marks and stamps I've found on the holster. I didn't find any date stamp but it looks like possibly the tops of numbers 1917 or 1918 under where it says "Berlin". It does appear to have some sort of repair or modification done, which I have included pictures of at the end. That's about all I came up with and hoping someone can correct me or provide further insight.

The pistol came with the correct fxo & e/37 black bakelite bottom magazine, but also came with an extra magazine. I believe it's a blued tube, aluminum bottom, however it has two serial number stamps, and one has a prefix (not suffix) of "N". I have to been able to find any info on this except a possibility of it having to do with the Navy or a Northern Naval base. I've included pictures of the magazine for reference.

Thanks in advance for any information provided. I look forward to learning good information about Lugers on this forum.
