Csiford, congrats on your first Luger and welcome to the forum. All the numbers showing appear to match, the finish appears to be reblued due to earlier roughness and piting. The holster is unique to me; I've never seen one like it. Show us close photos of the mag and particularly the bottom. Photos of the back sides of the grips will be helpful in determining originality. Nice first rig.
My opinion is that you may have paid close, if not slightly more than the market value. Frankly, you did ok on your first Luger purchase given your limited knowledge.
I'm sure you will enjoy your new Luger, the most famous and exciting pistol ever made.
