The Shadow Knows that is was not a Leichtenstein proof lurking on the right side of my Luger. It was a famous gunsmith by the name of Fluckiger in Zurich, Switzerland that stamped his trademark an enrayed Federal cross and F Z for his initial and city enclosed in a bow as in bow and arrow. This gunsmith refurbished an unknown but small quantity in 1923-5. Their distinctive barrels may recognize these with a special front sight by Hammerli of Lenzburg. All the pistols he worked on where rebuilt and refinished to his satisfaction.
