Lapogus,
During the 1990's I had several opportunities to visit the Liege arms museum in Belgium. For me the most fascinating gun on display,was the 17 barrel gun made the English gun maker Dupe of Oxford. This superb one of a kind gun should surely be in a British museum.
The gun was made circa 1800 for that redoubtable sportsman, Colonel Thornton to whom credit is given for opening up sport in the Scottish Highlands.
Perhaps Birmingham & Liege could consider a trade?
