Better picture would give a better indication if the Mauser was reblued. A lot of "speculation" until that happens. This 1914 has seen a lot of use but still a nice example of a well made German pistol. Value, 250/ 275 Imperial marked (Imperial mark in front of rare sight) and in excellent condition 425 450. I own twelve 1914s and 1910 Mauser pistols. (A quality made early made German pistol.)
