A friend just picked up a nice Baker Sterling single trap gun, made around 1912. This is the model that has the barrel and vent rib milled out of the same piece of steel. The bottom of the barrel shows the Krupp fluss stahl -essen [sp?] markings which is not uncommon, but it also shows the Belgian marking LLH. Neither mark is the type of mark "added" to make the gun seem better. How do the LLH and Krupp marks relate to each other ? Did LLH sell Krupp products at one time ?
