I set this up for the 4th at the local fairgrounds with some help from fellow collectors. My idea was to have a top (coat, shirt, etc.) and helmet from 1918-2018 on display. I ended up with 11 tops and 16 helmets. I displayed some of them upside-down to show the evolution of the suspension from leather to cotton to pads in the ACH. From one corner around counter-clockwise was 100 years. I had to use some repros as this was an open display and putting an original WW2 paratrooper helmet or uniform out seemed like an unnecessary risk.
I ended up with WW1 top, M1917, M1917A1, WW2 M-1937 shirt, M1, M1942 jump jacket (repro), M2 (repro), HBT top, M1 with burlap cover, OG fatigue shirt, M1 w/OD cover, M1 w/Mitchell cover-fall side out, Vietnam slant pocket shirt, M1 Mitchell cover, M1 w/ERDL cover, BDU coat, M1 Woodland, MMH II, 6-color DBDU top, Kevlar w/6-color cover, Kevlar with winter white cover, DCU top, Kevlar w/DCU cover, ACU top, MICH w/ACU cover, OCP top, ACH w/OCP cover.
