Finally Joined The Luger Fraternity Today!

[MGWLLW]

I've collected military surplus firearms for many years, but finally got around to adding a P.08 to the collection. It's a 1918 DWM with original finish & matching numbers, except for the mag & unnumbered grips. I wanted a shooter that wasn't messed with and this pistol fell in line with my budget. I do have a couple questions, though. And if this is the wrong part of the forum to pose these questions, I apologize in advance.

1. Does anyone know what the capital "K" on the left side (after the serial # and above the takedown lever) signifies?

2. Would this pistol have originally come with walnut grips numbered to the gun? The ones on it now appear to be beech and are unnumbered. Can I assume they're replacement commercial or repro grips?

3. In regards to the import mark above the trigger guard, does anyone have an idea where Simpson would have sourced these lugers from? Private collections in Europe or former military/law enforcement stock?

From reading the vast amount of information contained within this forum, this gun appears to be just your run-of-the-mill WWI military luger. If anyone sees anything that I missed, please point it out. I'm really looking forward to learning more about lugers from all the knowledgeable members on this board.
