442ndRCT Soldier's Forum

Interesting - Helmet Liner with 133rd crest paint on it, togehter with the Red Bull emblem. Probably not period, but still nice just the same

Stuff like that was normally done post war. The tip off on this one is the Korean era sweatband. The rest of the helmet is WWII vintage. Insignia was done like this in mass for the coming home parades for returning war veterans. I've got pictures of many 442nd also doing the same. I would guess this was used as the same then after was kept in service and the insignia was never removed.

Very cool though and I would consider it a war collectible.
