My wife picked up a late Christmas present (read for her) for me, on her way home from work. An H&R 922, 6 inch, 9 shot .22. SN has an AH prefix, (AH724XX), located on bottom of the grip, model number on the left side of the barrel, company name and address on the left side of the frame. Gardner Mass for the address. Anyone know about how old it is? And she got it for.$150 OTD.
