Larry;
Do you know if perhaps VL&D sold guns under the KnockAbout name from both Francotte & Sauer at the same time. I was thinking they would not have used the same name simultaneously for two different guns, but then? Perhaps they did sell a sidelock & a boxlock both under the name Knockabout at the same time. I feel certain the gun in quesation does date beck into the 1800's but did they continue the basic gun to a later date.
