Robert; I think you have it there. Also unfortunately all makers do not always follow the same terminology & meanings change over time. A very good example of this is "Double Action Revolver". "Originally this meant a revolver which could be fired by either of two action types ie by either hand cocking or firing by a long trigger pull. What today is referred to as "Double Action Only" was then a single action, as it had only one mode of firing ie by a long trigger pull.
Chopperlump was I think primarily a British term, they were I think the only people to call an axe a chopper.
