I have an old W Richards side lever opener which is chambered for 12ga & has the bores marked 14. It was built prior to chamber marking so does not have the nominal chamber marked. Bores now measure just under 13ga, so have no real idea as to just what they were when new. Proofs are Birmingham as best as I can tell, could be counterfeit.
