Is it a breaktop or does the cylinder swing out? On the barrel there should be a caliber designation. It could be something like .22LR, .38 S&W, .38 Special or similar. My father had an old H&R breaktop in .38 S&W with a 4 inch barrel. I believe it was a model 926. Any description like barrel length, break top, swing out cylinder or anything will help.
