My 13 year old hunting buddy brought me a fllipietta 44 cap and ball revolver that his grandfather found .It has a brass frame and a 12" barrell ( i am quessing ). The cylinder does not rotate when you try to cock the hammer back. so I just trying to figure out why . I took out the plunger assembly (Do not know propper term) when it is removed the cylider acts as it should .I notice the cylinder quide rod has a flat side and when the cylider rotates it hits where the plunger assembly screw is. Other than this the revolver seams to function fine . It needs a good cleaning . I have no exeperence these revolvers as was wondering if any of you have had this experence and how do you get the cylider out for cleaning .Any help advice and precausions appreciated. Thanks
