Hi, I am hoping someone can help me identify my revolver. It is a solid frame, nickel plated, 7 shot with an octangular barrel. Barrel length is 6". Markings on the barrel are "H&R ARMS COMPANY WORCESTER MASS USA 22 RIM FIRE" On the top strap it is marked" H&R MODEL" over "1886 22 CAL RF". The 1886 is a guess, the top is a little worn. The serial number is 70382. I have searched the net and can't find this model listed. The revolver is in pieces because when I got it, it was not working (not reassembled properly) and I need a schematic to try to get it back together ( if all the parts are here). Thanks for any help you can provide. Mike
