That is one spectacular 1900 American Eagle Luger!
Every gun nerd (I hate the term gun nut) needs to own a Luger at some point in their journey of firearm study. Mine is a DWM WWI military issue with a 1916 chamber date. It came with a nice 1939 dated hard shell holster and a couple of fxo stamped WWII vintage magazines. It has all matching serial numbers (except those mags) and is in decent shape but nothing like the OP's.
