I need a barrel for a Remington .22 that has no model number. The serial number on the action is #228514. Just about the S/N are the initials "RW" and behind the trigger guard is the name Remington and the initials UMC in what appears to be a trade mark symbol. The S/N range as found in the "Blue Book of Gun Values" suggest that it is a model 1889. But that same book shows a Model 1889 to be a shotgun.
