I though I might add that the patents on things plays a big part in what is a vintage.
Classic represented things that were in high demand by consumers and become collector items when they are no longer made.
U.S. Patents filed after
June 8, 1995 expire 20 years from the date of filing.
U.S. Patents filed prior to
June 8, 1995 expire 17 years from the date of issue, or 20 years from the first non-provisional patent application in the family - whichever is later.
