Factory letter lists revolver with 4" barrel in .45 caliber, blue finish and wood grips when shipped to Simmons Hardware Co., St. Louis on March 18, 1897. With SAA one piece walnut grip. In "A Study of the Colt Single Action Army Revolver," only around 1,000-1,200 of these "ejectorless" revolvers were estimated to have been manufactured with the majority of the production occurring before 1900 (page 69). Per Keith Cochran in "Colt Peacemaker Encyclopedia, Volume 1," only 494 out of a grand total of 1,000 "ejectorless" SAAs were manufactured with a 4 inch barrel (page 370).
