Refinished ?
 

Hi,

The safety catch appears to be blued not stawed which leads me to think the pistol may have been refinished at some point.

Safety levers often grow dark over the years from interaction with skin oils, etc. They are the most handled straw part on the pistol. A safety lever which is darker than the balance of the strawed parts is not unusual.

Every luger has a tale! Excellant read!!

Ron Wood your amazing, you sure know your stuff.

One pic is showing vastly different tones of the finishes on the frame and upper. The toggle axle retaining pin also looks blued. A check of the interior of the gun can be made when it is field stripped, to see if the bluing is properly absent within.
