Larry, I was quoting from Wirnsberger on the 12/C and 12/LC rules. I have a W. Betts pigeon gun with 12/C, three inch chambers, and proofed for 1 1/2 oz and marked 3" on each barrel flat. It was made in the 1920s, I think. One often sees British guns, especially Greeners, chambered for 2 1/2" shells and 1 1/4 oz of shot, but I don't think I have ever seen 2 1/2" chambers proofed for 1 1/2 oz. of shot in a British gun.
Englehardt seems to be wrong according to examples like above. Also have a Cashmore Nitro marked 12/C and and "3 inch cases". Have a Greener Monarch Imperial marked 16/C and "2 3/4" case". Both of these markings seem to contradict Englehardt as you quote him.
