I bought some used Colt mags for a dealer by my parents house. When I got them home and started to replace the black followers with green ones, I ran into a couple of different mags. One of the bodies have a 5 digits stamoed into then, 62667 I think. The other had a very dark green, but not black, follower this some white numbers on it. The numbers are kind of worn, but it is readable. Any insight into what I have? Thanks eagle308us.

50 bucks says you have 67 Colts.  They are any early 30 round magazine by Colt and should have matching followers too, dark green or black with numbers also.  Just as you described.  They are a desired mag by some.
