The real tragedy here is that whatever moron removed the barrel (any barrel that doesn't have the side blown out of it can be restored in some form) has destroyed some history in the process. Looking at the engraving, and taking into account the time of manufacture and other markings, I wouldn't be a bit surprised if the missing barrel didn't bear the name of Charles Lancaster of London. Lancaster was the official Britishicon agent for Ross in the early days and licensed to build rifles using Ross actions, many of which were stamped with the New Haven logo. This probably started life as a .370 Nitro Express English-built sporting rifle, possibly for an African hunt. And I still envy you.
