In JROTC I learned the disassembly and assembly of the BAR as well as the M1 and Carbine. My uncle was a squad BAR man in France in 44. I was referring though to the fact that the ma deuce will be in service for another 20 years and several Spec Ops units still use the venerable 1911. Heston must have some collection. I’d love to see it.
At one time I could field strip just about any pistol quickly with one exception. The Ruger Mark 1 .22 pistol was so tough that I finally just gave up and cleaned it as well as I could without stripping it.
That turned out to be well enough as they never gave any trouble.
