According to Greener in his book,"The Gun", 12/C was used to denote chamber lengths upto 3 inches. Above 3 inches the 12/lc mark was used. If a gun is nitro proof the shot load given is a good indication of chamber length;.For example 1 I/8 OZS;=2 1/2 chamber.1 1/4ozs;is almost always = 2 3/4 chambers.

2&13/16's If my math is right then thats.812".Under British proof rules there max depth of a 2&3/4" chamber is 2.850". So the gun would be in proof on the chambers length .Had another look at the photos and it still looks like black powder onnlt. Are the barrels in good condition? Good wall thickness and bore size?

The nitro proof stamps are on the far left, and not very legible in my poor photograph.
These are heavy Whitworth barrels with bores of .733/.733 in excellent shape.
