Truth be known, many of the "big name" London guns were and are made with parts generated in Birmingham and other towns in Great Britain, especially boxlocks. These normally are sturdy well made guns but have the extra clout of having a London name engraved on them. As Kensal pointed out,to a large extent, you are buying the name along with the gun. To give an example:
I own a matched pair of 12 bore guns by Elderkin & Sons. They have 25 inch barrels and nicely rounded boxlock actions. They look identical to Churchill Prodigys and IMO are equal in quality, but I bought them for less than half of what I would have to have paid for a similar set of Churchills.
