Buying a British gun based on name is like choosing a lady based on the dress she is wearing. The quality and value is what is under the dress or name in this case. The thing that makes it more so was the tendency for name makers to bring in lower grade guns from the trade and finish them or just have their name put on them.
Buying a British gun is real simple when you think about. Does it fit you? Is it in good condition? Does it appeal to you? Will it do what you want? If not pass. The name of the top rib or the action side never made a gun shoot better anyways. Never buy a gun looking for resale value alone. Buy to use and be happy.
