From a working gun perspective- I own a forerunner of the Knockabout, which was built in 1891. These were VL&D boxlocks, not stamped Knockabout. The gun I have is balanced well and has terrific triggers, some engraving, and well built 30 inch damascus barrels. It is a good shooter, bored IC and IM. It has 2-5/8" chambers, now with long forcing cones. I like Francottes of this era.
