This is a very nice all original  Finnish M39 Mosin Nagant Rifle that was manufactured at the SAKO Arsenal in 1943.  Mechanically this rifle is in excellent working order. I have personally fired it and it shoots great.  This rifle is SKY marked on the barrel shank.  It has a beautiful original SAKO cartouche on the right side of the stock.  There is an import mark at the end of the barrel.  These are excellent rifles and highly sought after in the milsurp collecting world.
