The first two digits of the serial number are the production day (10th day), the third character is the month (E = May), and the fourth and fifth characters are the year of production (presented in reverse, so 27 = 72 for 1972).

This is a legacy serial number format.
Example Serial Number

Version 4

The final four characters are what we focus on. The first two are the year of production (04), and the final two are the week of production (11th week). That would make this the 11th week of 2004.

This is a legacy serial number format.
Example Serial Number
1 2 3 4 5 6 0 4 1 1
This would read as being manufactured in the 11th week of 2004.
