That's my M-26.....cable, rod, strap, they were all improvised with what was available Korea only...WW II hadn't got to that point. The reason for so much mg ammo was due to the vast hordes of Chinese attacking in 3 to 5 waves, which rapidly ate up all the basic load in a hurry. Also many spare cal 50 barrels were carried as they burned out fast. I had 9 on my tank, all marked with the # of clicks for proper headspace. These were normally found in one of the long sponsons.

Here's a typical example....appologize for the blurred photo....all I have, but shows a cable setup...it works.
