I recently acquired a 1964 model Colt National Match 45 auto. It is in excellent shooter grade condition. In my reference book I noticed in 1965 Colt started putting the Elliason sites on the NM models. It did not have a good pic of the the adj site on the pre-64 models. I am pretty sure the adj site on mine was added sometime in the previous 47 yrs. does anyone have a pic of a Colt National Match 45 that shows the Pre-Elliason adj site? Thank You krw
