Need help with my Luger!

[Syxtnyne]

Okay, so I'm new to the Luger world. It's probably obvious because I'm here with a title to my post mentioning that I need some help. For starters, I was told this is a Mauser Banner Police model. I was told that it is almost all original with the exception of the grips and the one part that isn't numbered to the gun which I was told is the sear bar. I was told that by Eugene at Luger Man. I'm sure there are a bunch of other little parts that have numbers on them, but I've never taken a Luger apart so I need to research that real quick. Yup, newbie.

I apologize for some of the pictures either being flipped or a little difficult to see. For the parts that I tried zooming in on, my camera refused to cooperate.

For the smaller parts that may not have shown up in the pictures:
-Barrel: the barrel has a number, 883 on it.
-Safety: has the same 26 number on it.
-Serial Number: just above the number there's a little eagle looking mark.
-Frame: on the side of the pistol (right side) there's an Eagle with an L on it.

I just would like to know if anyone can tell me what exactly I have, how correct it is based on the info that I have provided. I am also on the lookout for grips with the number 26 on them so that I could replace the ones I have for a set with the correct number on them.
