LOOKING THRU THE OTHER PICTURES I FOUND A VERY FUNNY HELMET. IT LOOKED JUST LIKE A COFFEE POT WITH LOTS OF HOLES AND THE SPOUT FORMED THE NOSE, PERHAPS IT WAS THE ORIGINAL POT HEAD
ANOTHER FUN ONE APPEARS IN YOUR PICTURE #5 IT IS THE SMALLER HELMET AND IN ONE PICTURE IN THE ALBUM LOOKS LIKE C3PO FROM STAR WARS.
