Newbie with a mag question...

[donmor53]

Hello from Texas guys,

I'm new to the forum and after years of gun collecting I have take the plunge and bought myself a 41 byf Luger (s/n 1449a) and a Mauser C86 Red Nine from a friend's collection. My initial question is regarding the magazine that came with the pistol. It is an FXO, straight eagle 37 Top and bottom of the left side) that is in overall fantastic shape IMO. As you can see in the supplied photos...the pinned aluminum bottom has been stamped to match the pistol somewhere in the past. I've gotten answers all over the map regarding the authenticity of this mag actually matching the weapon. I've heard everything from "Bubba work" to "armorer's repair" to "original issue". Since there are no other proof stamps on the aluminum...I honestly do doubt it being "original issue". I guess my question is...what do the resident experts here think? All input would be welcome

Below are is photos of the bottom and side stamps and the rig as I got it...
