I don't know much about shotgunning or shotguns in particular, other than the basics. I was talking with a friend of mine about skeet shooting (we're both new to this stuff) and he was asked a question by one of his associates who knows quite a bit. My friend had seen an o/u that he particularly liked and was discussing this with a friend. Said friend asked "what country was it made in, and what class was it?"
I know that the country of manufacture is often a selling point, especially on higher end guns, but what does class refer to? Level of workmanship? What shooting sport it was designed for?
