The 39A and 39M Article IIís were made to commemorate 100 years of the NRA in 1971. I assume Article II refers to the second amendment to the constitution. They have a medallion on the side of the receiver. The fore-hand cap and the crescent butt plate are brass . They have an octagon barrel. They are very similar to the Century limited. The difference is there were only 6,265 39A Article IIís and 3,824 39M Article IIís where there were 34,197 Century Limitedís.
