Barrel comes off with a quarter turn. So an H or TD H would only have a shotgun butt? Barrel address is as follows: top of barrel 25-35, Manufactured by the savage arms company Utica NY USA. second line reads --- PAT Feb 2 1893 . Oct 3 1899 May 25 1909 June 1 1909. Left side stamped Savage Hi pressure steel Model 1899. I didnt know they made 1899 A s in take down model. Thought they were too early? Ser # not stamped any where else on gun except bottom of reciever. Only guns I have ever seen that were cut down had flat bores but Im only 49 yrs old. Still wet behind the ears I guess. Thanks for the inquires
