my list shows h&r used "ax" in 1981. but 81 or 82 does not matter that much with it comes to the owners manuals given with these revolvers. they were little more than how to load and unload no parts list or drawings. i do have one, it is one page folded in half to make four. best parts list and drawings are in the numrich arms catalog and i believe it is available on line at www.e-gunparts.com
the value 22wrf gave you is right on for my part of the country.
