The T-1 Pedersen Rifle
The Pedersen Rifle, officially known in final form as the T1E3 rifle, was a United States semi-automatic rifle designed by John Pedersen that was made in small numbers for testing by the United States Army during the 1920s as part of a program to standardize and adopt a replacement for the M1903 Springfield.
Although the Pedersen was rated for a time as the most likely candidate for standardization and adoption, the .30 caliber M1 Garand rifle was chosen instead.[1]
I think they made the right choice. Nice gun but not a Garand.
And the M41 Johnson rifle. Also, a light machine gun by the same designer, both of which saw action with The Devil’s Brigade in Italy.
