Mike is correct.
The guns were built in the trade in Birmingham and would have been sold at the London Sporting Park , presumably to clients of Watts', who was a noted shooting instructor. I guess it is similar to the modern endorsements like the tennis racket editions named after top players or the lines of perfumes or clothes launched by the likes of P. Diddy and David Beckham. It looks like a name could sell a product even back then.
Some Webley-built boxlocks appear with 'London Sporting Park' on the actions and ribs as well, so they must have had a gun-retail section to the shooting grounds for some time.
