I am a little thrown by what I'm seeing and reading. The ad does not actually say these are made by Holland & Holland, yet lists the manufacturer as Holland & Holland. Did they make a gun marked H&H like these? The letters confuse me too - it makes it look like the model of the guns is "shot and regulated". And if not, how does one regulate a shotgun after its made? I do not have enough experience to know what I am actually looking at here.... thank you.
