We found an old pump rifle...a Remington-UMC 44...still works...belonged to Grandfather. Looking for information on the gun using the serial number, etc. Remington site had no info...it does not show a model number...on barrel it has " 44 rem or 44 W.C.F." Any hints where I might find out date of manufacture, etc. Butt of gun has Remington-UMC on it...thanks for any leads.
