Since you do not say, whether your Harrington & Richardson is a pistol, rifle or shotgun and you do not show a letter prefix to the serial number, I can only give you limited information based on a Model 48 Topper Single Shot Shotgun which was manufactured for a period of 14 years between 1943 and 1956. I hope this helps, until you can supply more information on your shotgun.
Depending on condition, $100-$150.
