From the mag FAQ:
[2-2-1-1] Early Colt 30-round Mags
Army and late Air Force contract mags. The first Colt 30-round mags had dark green, hard-plastic followers with Colt part number 62665A stamped in white on the follower and part number 62667 stamped on the side of the body. These followers did *not* have the lengthened front "anti-tilt" leg that later green followers have. These mags are rare and collectable, though considered unreliable by some. Made from 1967-1969. Floorplates stamped:
