Re: " If memory serves, the Garand was the smaller and lighter carbine",
The M1 Rifle was called Garand, ie, named after John Cantius Garand, the designer.
As for the carbines.......
"Despite being designed by Winchester, the great majority of these were made by other companies. The largest producer was the Inland division of General Motors, but many others were made by contractors as diverse as IBM, the Underwood typewriter company, and the Rock-Ola jukebox company".
From here: http://en.wikipedia.org/wiki/M1_carbine#Production_and_usage
The M1 Carbine was single shot semi-automatic. A later version, the M2, was adopted with an option, providing a fire selection for full automatic.
Nice story, though.
Long Shot: Man finds rifle his dad used in Korea
"... Virgil Richardson fondly remembered the .30-caliber M1 Garand rifle he carried during his time as a soldier during the Korean War.
He even still had the weapon's serial number.
Using that number, Jim Richardson went online and found the firearm at a Kentucky gun broker. ...
Virgil Richardson said he'll wait until his Oct. 26 birthday to shoot the weapon.
"What shocked me the most is how very heavy it is," he said. "I have trouble now holding it up and aiming it. I guess they were made for 20- and 21-year-olds."
If memory serves, the Garand was the smaller and lighter carbine, given to radio ops and such. The M1A1 was even heavier.
