Gentlemen,
Like I said, I thought that the grip/lanyard modification was Norwegian, but I do not have much to substantiate this theory.
However, the vast majority - if not all - of the FN 1910/22 pistols found in this country today are guns that were brought here with the German invasion and occupation 1940-45. I find it quite unlikely that one or several guns used by the Norwegian armed forces could have been to France after the war. We had such an abundance of ex-German and Allied pistols that we didn't even have to think about acquiring new ones until the mid-80s, when we settled for the Glock 17 to replace all the M1911s, P-38s, FN Brownings, Lugers and several other models that were left here after the war. This is the reason why I still believe that the modification on my gun, if it is a post-war job, was done here in Norway. The modification may very well have been adapted from France - or vice versa. I have no problem seing the need for a pilot to secure his sidearm in addition to the security provided by whatever holster it is being carried in.
Respectfully,
Balder
