After the German U-Boat Kapitan Walter Schweiger sunk the Lusitania, they became even scarcer. But from 1908 until about 1916, Krupp Flusstahl (fluid steel) barrels were commonly found on: LeFevers, Ithacas and AH Fox guns- not so much on LC Smiths--beware- some sellers will over-use the "rare" word- there's a few on GB hawking way overpriced _IMO anyway_ field grade LC Smith 12's with "scarce 32" barrels"--they'll do anything to sell a gun to you--
