Cool,
sorry I am so late in getting back with you. I would ignore the 'elevens' on the grips. I cannot imagine them having any significance. The '2' may just be an inspectors mark. The SSN may be a different story and I would have to see it to see if it would have any or much price significance at all.
For your information, Ron Wood is correct in stating that Jan Stills reported fewer chamber dated 1916 navy Lugers than 1917 chamber dated navies. But Jan Stills also reported a number of chamber dated 1918 navies. I have never seen a legitimate chamber dated 1918 navy. To my knowledge, all of the chamber dated 1918's that have been reported have had their chamber dates challenged. I believe that the model number 1914's that were made in 1918 were manufactured under a 1916 navy contract and, therefore, had that contract year impressed on the chamber. So the number of model number 1914 manufactured in 1918 would have to be added to the number reported as 1916 chamber date to measure the scarity/rarity. But its meaningless to discuss numbers manufactured because ALL navy Lugers are highly desirable.
Also remember that I was the first to make a bonified cash offer for your navy and my original offer still stands
Your very good friend, Big Norm
