Here are a couple pics of my Kirkwood Bros 10ga apart. It has steel barrels and the only proof marks are the ones shown on the barrels ahead of the flats. This gun is not like a lot of the cheaper "put your name on it" (ie Clarbrough sp?)guns from England that I have seen before. It is of higher quality and really a nice gun. Does anybody recognize the design as that of an English maker? I like to think the barrels were brought into the US and the rest of the gun made by Kirkwood, but I dont know. Ross
