Tom-

Here is the info I have-

  • Prior to 1984 there was not a date code included as part of the serial number. Starting in 1984, there was a four digit date code following the serial number that was month and year. Example – JO-12345-1084, this unit was built in October of 1984. Starting in the year 2000, same idea only it was a six digit date code following the serial number that is year and month. Example – 1234567-200105, this would have been build in May of 2001. Anything without the addition to the serial number would have been made before 1984 and would require contact with the factory.*

Hope this helps.
