I've got two Orecks that I need to find the age, a 2600 and an XL21. The XL21 has a Date stamp of 03329, and the 2600 has a 5 digit code (which I'm assuming is the date) of 00082. A post in the archives said that the first two digits were the year and the last 3 were the day the vacuum was made, but that would mean that the XL21 was made in 2003, 2 years before the vacuum was released. How do I find the age of my vacuums?
