Dave, you left out the emotional attachment many double owners have for their guns, with a heritage, a feeling of belonging to and being a part of a particular place and a particular time, a pride of having guns owned by a sort of classless society where the affluent had higher grades and commoners the lower by the same maker, when people were valued generally more for what they could do then their parentage. To some it is a craving. I'd be a poseur with a Purdey.
