H&R Arms 22LR 7shot revolver
I'm new to the forum so I hope I am posting this in the right place.
I was recently handed-down a H&R Arms 22lr break-open 7 shot revolver. I am struggling to find much information about this gun. All my grandmother could tell me is that it belonged to my great grandfather and she thinks he had it from when he was in WWI. Other than H & R Arms, Worcester, MASS, U.S.A. on the top line and 22 RIM FIRE on the side of the barrel, there is no model information I can find. There is a serial stamped into the butt of the gun, 9024.
I would appreciate any information anyone can give me in regards to what model this is and an approximate age.
Also, it is in need of a little bit of a clean up. Cleaning the barrel and cylinder are no problem, but are there any other measures I should take? Some of the finish is gone from the cylinder, exit of the barrel, and a few small spots elsewhere. I know this is never going to be a pristine gun but it is a family hand down and I would like to keep it in as good of shape as possible.
