Hi everyone. I am hoping to find out some information on this gun. It belonged to my grandfather. This is the information I have. Pat date Feb 27,00. 44 caliber stamped on top of barrels. It takes brass casing shells. Cock trigger. Has Harrington Richardson Arms Company, Worcester, Mass, USA stamped on it. Here are some pictures. Any information would be appreciated . If its rare, value, etc. Thanks, Lefty
