Date codes are stamped, either by being punched or ink stamped into the hoop. The embossed numbers on the back of the spokes are copyright info. Depending on the year of the wheel, will determine where it was manufactured. Some say Mexico, some say USA, some say Firestone. Don’t be fooled into thinking you have a 1964 wheel due to the numbers that are embossed/cast on the backside of the spider/spokes…many do think that, but it isn’t so.
