Re: M2 carbine won't run
They often re-use the same film clips, one show about the P40Warhawk showed a pic of an early P51 Mustang. Guess they think nobody will know the difference.
The show I watched said 1938 for the Garrand and late 1942 for the Carbine. Some old vets told me that the Carbines didn't show up till late 1943.
All I know is that with the military's reputation of supplying decent firearms in times of battle, GI's were lucky to get the M1 in time for WW2.
