I was searching for Articles on Barrel making and found this Paragraph on an American site. A Poignant reminder of the UK`s decline - especially the last Sentence!. Great Britain, once the home of a vast gun trade centred in London and Birmingham, now only has two barrel makers; Border Barrels, who have a production shop mainly serving the industry and a custom shop for specialist barrels - and Arms Restoration Services who specialise in the larger calibres, particularly 19th century black powder types. There is now no national ordnance factory barrel making facility. The UK can no longer make new assault rifles for its army.
