My grandfather had an old .32 revolver that felt like it was made of plastic. Had no markings on it at all, wouldn't lock up at all hardly. A friend of his bought it for $5, my grandfather bought it from him for $20 just to get it away from him. He wouldn't even keep ammo for it after the first time he attempted to shoot it.
He wanted to put it in the fireplace and destroy it, but held onto it just for the heck of it. He said it's more likely to kill the person holding it then to actually fire at an intruder.
He also had an old H&R revolver .22, maybe the same as yours. He loved that thing, but made sure he kept 5 beans in the wheel. Or 8, I think it was a 9 shot.
