The Knockabout comes from an era where most name brand guns were sound and shootable. Variations in quality had mainly to do with finess of finish, engraving, and wood quality. The Knockabout tends to minimal engraving and relatively plain wood. It is finished at a very servicable level, but far from a best work level. It is on par with the middle of the pack Brit BLE's.
