Point of correction here. If the barrels are marked Fluid Stahl, I would suspect a counterfeit. Krupp Flustahl Krupp Essen would be the more commonly found marquee, and after the Lusitania was sunk, and America's relations with Germany started to wither, few Krupp Flustahl barrels were exported to the American gun makers. I have 2 early A.H. Fox graded guns with Krupp Fluid Steel barrels, and one graded Parker with the Whitworth Fluid Compressed Steel tubes- each tube has its own identification number. Prosit!!
