H&R "SPORTSMAN" double action .22

[45Auto]

I have a 9 shot top-brake revolver marked as follows:

left upper barrel flat: H&R "SPORTSMAN" double action (in two lines)

right upper barrle flat: Harrington & Richardson Arms co. Warcaster, Mass, USA

right side of barrel in front of cylinger: 22 LONG RIFLE CTG.

The serial No. is located on the front side of the grip strap, which would be visable w/the one piece grip in place. The serial No. is also located on left side of the frame under the grip. Also on the left side, well below the serial No. is a capital letter F. The grip area of the frame is shaped like a half moon. There is a screw hole in the back of the grip frame to hold the grip on. The wood grip is missing.

The firing pin is part of the hammer. It has coil springs. 6 inch barrel.

My questions are as follows:

When was this revolver made?

What model No. is it?

Are the parts compatable with other models?

I'm looking for information to use when ordering parts.

Thanks,
Greg
