Maybe I didn't phrase my question correctly so all could understand it, so I will try it from the opposite side. Did any of the English houses list themselves "at the time" as a gun maker or gun manufacturer who never actually made or assembled a gun themselves?

I know that gun lovers today know that all English makers didn't make their own guns, I know that the name back then was an assurance of the best product whether made in house or not, and I know that many many USA companies, whether Weatherby, Browning, Sears, etc. etc. had/have guns made to their quality specs with their name on it. But I don't remember that Sears ever called itself a gun maker.

This is not a finger point whatsoever. I just want to know that if an English house in the 19th century called itself a gun maker or manufacturer, it at the very least meant that it had assembled at least one of its models at one point in time to use one of those descriptive terms.
