eisman, Not necessarily. I have just looked at 4 fixed blades from the 1950-1960 era, and all are marked "Solingen, Germany" or "made in Germany". One is a Fred Mac Overland, a Doppelreh (Double Deer), a Thalson, the last. a Gazelle, made by Krusius and marked "Solingen Germany British Zone. That one should be prior to or around 1956, when the "British Zone" was no longer in effect. John
