Any info on my new old gun??
My late grandfather left me a couple of guns when he passed away. The one that I have questions about is a .410 single barrel folding shotgun made by harrington and richardson arms co. The serial number begins with an "A". I previously read that all folding guns from the same manufacturer began with an "F". I know for sure that it is pre-1940. I would like to find out how old the gun is and possibly the value...If anyone could help it would be much appreciated. I also have an octogon barrell pump .22 that I would like info on too. I dont have the make or model for that with me. Thanks guys
