The gun has been restored/refinished.
The barrels and other parts have been just re-blackened and is dipped in oil, hence the look.
The case is a new genuine leather case that has not been fitted to the gun, I hope I will do that soon. I have a label with the 126 Strand address but could not find one with the Molton St. address. Any help will be appreciated.
Nick Makinson restored it for me, he has asked me for pictures and it will appear on his website shortly. He is a Birmingham gun maker with a lot of experience on Birmingham guns and he has also built a few double rifles. It cost me much more and much longer than what I had expected, I have other British SxS's which did not need any work, but love this gun more because of the involvement required. It was a very satisfying and wonderful learning experience and I don't regret it . If needed I will do it again if I find a gun like this that needs work and can afford it.
