My Wild gun is marked T.Wild,Whittall Street,Birmingham.It is a .12 bore w/28" barrels and weighs 6 lbs 9 oz.It is proofed at 3 tons,2 1/2" chambers opened to 2 3/4" and re proofed in Birmingham.I shoot low pressure (6500 psi) loads in it in 50 bird events several times a year and it handles very well.I probably put 700 +/- minus rounds through it a year as I have 1/2 dozen English sxs's and shoot them all.
