You'd be surprised how many Best guns were built in Brum. All the research I continue to take in says many top London makers used Birmingham trade which were simply some of the best in the World so it doesn't matter to me really...If it's a Wilkes it's a Wilkes because wherever it was made it was made to a standard that was acceptable or beyond the makers criteria.
Having said that it does seem a tad expensive for a sleeved example. I'd sell my Lancaster Sidelock for that which I think is a nicer gun and has original barrels.
