W. Richards is still in business but now at Pocklington, Yorkshire https://www.wrichardsguns.co.uk/ Here is a similar one at auction in England. https://www.the-saleroom.com/en-gb/...lot-eb15eb7e-2e73-4a54-bc55-b11f00af86b0 It is a needle fire Rook & Rabbit rifle. The serial number 1939 may be in their records as they still hold fairly complete books. Worth an e-mail and good luck. Lagopus.....
