What year was the transition made from the "flat head" (not 601 "fat head") firing pin to the current improved style? Thanks for any help

Quoted:
from Ekie's Guide: ArmaLite firing pin on top, current on bottom. Old part caused slam fires, and the new Colt’s design was put into production in 1963: http://img.photobucket.com/albums/0603/Ekie12091941/variation%20guide/firingpins.jpg I thought there were three types...."fat head", "flat head", and the current type. Am I wrong on that? |

Now I'd like to know the years the "light flat head" model was used. I hope m1sniper can find it in his book.
