Saw a re-enactors jeep today and he had both types of scabbard mounted to it. He only had one clip on the Garandicon and none on the carbine. I talked with him about it and he said that's how he always saw them mounted. The straps were directly fastened around the mirror post and tightened similar to a belt would be. The top strap with clip was wrapped around and clipped to the side strap ring. Perhaps the clips are primarily for horse gear?
