I'd guess they likely made more boxlocks that ended up wearing other names than anyone else. A lot of the guns sold as Army & Navy were theirs, and the origin is indicated in the A&N records. I had an A&N pair that were made by Webley & Scott. The Evans I now own is without doubt a Webley & Scott product from shortly after their merger. It's an Anson & Webley screw grip. And as far as I can tell from the Webley & Scott book, was the most expensive boxlock they made at the time. Clearly a gun that a firm with a London address would not hesitate to put their name on.
