This is a very nice all original British No4 Mk1 Enfield Rifle that was manufactured at Fazakerley Arsenal in October of 1948. Mechanically this rifle is in very good working order and is sure to be an excellent shooter.  There is an import mark on the side of the receiver. Post WWII Fazakerely Arsenal Enfields are some of the best shooting rifles on the surplus market.  Don’t let this one pass you by!
