Look up pretty redhead in the book, that one right there! Do a ceremonial cook on it, watch it turn magic purple, Great George Stephens ghost that is some pervature!
Thread...Red head appreciation society in the main Weber kettles and accessories threads. There's no such thing as too many pictures.
EDIT:
I was asked by a fellow member to guess the age... If red wasn't available yet in '58, based on the 1958 article Marty posted, then my best guess based on info thus far puts this between 1959-1961/62 or so... It's only an estimation and not set in stone. At any rate, that kettle is pure beauty!
