Pieper supplied "Finest Damascus" for Remington Model 1894 EE Grade guns and also "Oxford 4 S.J." The barrel makers were so skilled that they could produce this



Ernest Heuse-Lemoine (1834-1926) from Nessonvaux was a major barrel maker in the Vesdre Valley maintaining agents in London, Birmingham, and New York. Every 3 years he would travel aboard and upon his return, would be met by a band in celebration because he always came back with more orders than his own firm could handle. He would then distribute some of the work to smaller barrel makers. Gaier states that Heuse-Lemoine supplied damascus barrels for at least 50 years to US makers, and that he invented the names of "Boston" and "Washington" damascus especially for the American market.

Leopold Bernard barrels were highly regarded, but about every Belgian maker also produced Bernard pattern barrels
