Thanks for that Bob,but what I really wanted to know was if anyone could make a pair of barrels from chopperlump(side by side) or demiblock(O/U)tubes,machine and joint them then fit the ribs and finish them.It seems to me that there must be a good number of best quality guns in the USA with "out of proof" or very worn barrels that are not used anymore because they have become dangerous.Do people send them to the UK to be rebarreled or just put them away and forget about them?
