Hello out there! Yesterday's gun show find. I guess it's I frame .22 Kit gun. Serial # on bottom of grip, back of cylinder & underside of barrel is 19,8XX. Assembly? # on yolk & inside of frame, 73,6XX. Four screw side plate, coil spring, flat latch 4" barrel, blue finish. Perhaps I'm reading impaired but I'm not positive (reading Jinks book) of what I have is called & would like to know when made. THANKS!
