Put together by Springfield for the 1962 National Matches at Camp Perry, all the numbers match the article in the July 1966 American Rifleman. The slide is Colt all numbers are as they should be,of the pistoles made for the 1962 matches only 172 were sold by the DCM, I have owned this gun since 1968 and it is a dead on shooter. For sale for $3200.00 no trades, dont bump the thread PM me if you want more info or pictures. The picture of the right side of the slide and frame , I held it by a window and all the lines are from the screen not on gun.
