New to this and I am happy I possibly found a resource on h&r shotguns .I picked up an old h&r single shot from the local gunsmith it looked on the neglected in the corner.nobody has been able to tell me much information about the gun and looking for parts seems to be a challenge. There is no model on the gun . Only the brand,and the fact that has made in Worcester. Patent number February 27th 1900. I have numbers by the Tigger ...A342203... The screw is broken off the breakdown lever and that whole assembly needs attention . I don't even know where to start looking for parts for the gun.I would like to thank anyone that can identify the gun ahead of time. Nobody around here can tell me a thing about it.
