Long story short, my mom was redoing the interior in her 1987 RX7, pulled up the carpet and found this H&R 922. She has owned the car about 15 or so years and never knew it was in there. The grips are missing and it had some rust on it. I figured as a project i could reblue, make some grips out of wood and just go with it. It has the "bird head" or whatever its called frame on the grip and has the flat mainsprings. My brother tore it down and now wants me to put it back together. I have never worked on an H&R before and The only schematic I can find seems to be a later model with a coil spring not a flat screen. The serial number is F59** and Im not sure what year this was made. Any info or help would be awesome!
