I have been re-reading Yearout’s article on the “Aircrewman Revolver” in the July/Aug 91 issue of Man at Arms. In this article Yearout states the M13 (in the Colt version) was first issued in 1951. As I understand the M41 round was developed for the M13s and their alum. cylinders. What were the development dates for this ammo?? and when was it first issued?? What is the earliest M41 ammo head stamp that is known??
Thank you much
