Pauls12, So you can decode the years in the future, from about 1968, the first FOUR numbers of the serial number tells the month and year of the set. Another important LETTER is the Specification letter which is located on the ID tag. The "3cr" means that the set is capable of 120 or 240 volts. It can also be configured for full 4000 watts 120 volts.
