I pulled a H&R top brake 38 5 shoot out of the dirt today. I have no clue as to model, as I have not found a model # on it any where. All I have found is the man. with the following numbers, pet. 87may4 & aug 6 89, April 7 189? Ser # is D51992. It is as best I can tell missing some parts, and I would like to restore the thing if I can get the parts. Any help will be appreciated.
