WWII Carbine Holster

Made in 1943. Owned by "Joe W." Leather with steel. I think the idea was that paratroopers could come down with their carbines in a belt holster and if they saw the Indians circling the wagons below, they could whip out their rifles and pick them off their horses. I know you saw Indians riding around a circle of covered wagons in at least 50 different movies. Do you know there is not one documented case of such an event ever occuring? Not one. Good old Hollywood. Since its all fantasy, you might as well throw in some paratroopers gliding in instead of the cavalry charging up on horses. I use to think it was a jeep mounted scabbard. Now, I'm not sure. I do know it fits a mini-14 perfectly.
