A&W is a reference to 'Anson & Webley' ansd was used in teh trade to demote A&D boxlocks with intercepting safeties and with the Webley & Brain screw grip of 1882. These were made by Webley for the trade, including Army & Navy and William Evans. They can be very well finished and engraved.The sidelock generally used at the time was referred to as the 'A&R' for Anson & Rodgers'.

I noted in a Manton & Co catalogue of 1926 - 1927 that they were offering double rifles by Purdey. No reason Army & Nav could not do likewise. As to trade trms - I don't know.
