Many times the chicken pad would be removed when not in actual use because with a larger head, 71/4 for me, it makes the helmet FAR too tight. There was also a ring went into the top of the crown that is seldom seen...up above the webbing. These things also retain heat in summer. We did have a few that packed kit back from wherever they were, wonder if this one was turned in so the jumper could take his when he left. This one could then have been altered by the textiles tech so it was "Standard". Jumpers were supposed to return their jump helmet and draw a standard M1icon when they left the unit. Most didn't.
