Well, not so fast on thinking the MADE IN GERMANY is postwar. I have seen numerous, original German produced parts and original wartime tires (Continental/Dunlops/Deka and Fulda) marked with the Made In Germany. Yes it throws you when you first see it but the thing was English was the "business language" and in the inter war years products made for export (cameras, electrical parts, tires to name a few) would be marked as such. Now if it said Made in West Germany then its obviously postwar. Taking this one farther step I have seen Made In The U.S.S.R on BRDM2 tires. As edged weapons are not my area of knowledge I shall leave that for others to illuminate.
