The Colt Tritium Night Sight was announced by Colt on September 17, 1991. The images below are the two-page Colt news release for the Tritium Night Sight.

In addition to the Installation Instructions and Training Guide shown above, there is a ‘pocket size’ user guide also. This user guide is a bifold document that is 3-3/4 inches wide and 5-1/4 inches tall. The material that it is printed on is a heavy cardstock type paper and is laminated. The two scans below show all four pages of the user guide.

I hope you have enjoyed the look at this very rare and unique item. I hope to find an actual set of the sights some day.
