CAN ANY ONE OUT THERE TELL ME IF I HAVE THIS SERIAL NUMBER THING FIGURED OUT. I JUST GOT A SUPER 66 GAS (WITH 3 P.H. !!) AND THE FELLA SAID IT WAS A 1953.  THE SERIAL NUMBER READS 67607-606 
     I WAS HAVING A TUFF TIME FIGURING OUT THE BOOK I HAVE WHICH LISTS SERIAL NUMBERS, BUT MY WIFE, WISE WOMAN THAT SHE IS, SAYS IT IS A 1958.... I SUSPECT SHE IS RIGHT. THE CURIOUS THING IS THE 606 AFTER THE HYPHEN.... WHAT DOES THAT REPRESENT? EVEN SHE IS STUMPED.
               THANKS FOR ANY LIGHT YOU FOLKS MIGHT SHED ON THIS MATTER,
                             CAL
