Dave ,I think your theory is probably correct as you are referring ,but I have weighed just about every Parker barrel I have owned and came up with what Edgar is saying ,with Forend on and laying on an old egg scale almost everyone was the Unstruck Barrel Weight stamped on the barrels or within an 1/2 oz. . Coincidence ,maybe but pretty unbelievable ? We had a Thread on this quite a while ago ,I don't think we ever did reach a solid conclusion ! Makes for good conversation !
