As you will no doubt hear from your gunsmith, it is likely this Purdey was owned and bought by someone who wanted a gun he could use. Whether he reloaded or not, lengthening the chambers made it somewhat easier to find shells. Ignoring the maker's name for a moment, I bet you will find this gun will do what you want if you take care of it. And, the way the market works, you'll probably not be out too much for the privilege when the time comes to sell.
