Ladies and gentlemen, boys and girls - I don't think it's as straightforward as you might think. Why, for example, would someone be employed to polish a gun (if that is what the job was) - were they that obsessed with cleanliness and tidiness in the nineteenth century ?

I think it's something to do with the manufacturing process - a gun smith suggested it might be to do with carving the barrel and stocks. However, does anybody know ?

London and Birmingham were centres of gun manufacture at the time again suggesting this isn't just about making the landed gentry's shotguns shiny.
