Okay, guess I'll join in.
These were issued to my Dad in Korea.
I guess they were the first "Chemical Attack" Emergency suits... against Mustard Gas.
This is the only one he's got left. He says it looks sort of like a disposable rainsuit. It's still sealed, and I intend to keep it that way!
Anyhow, it's just one of the neat things he hauled back from the War.
