How old is my superpump motor?

I don't think that's the serial number... Hayward website says:

Hayward's serial numbers for all products, with the exception of some cleaners, controls, heat pumps and electronic chlorinators, are 17 digits long and begin with the numbers '21'. Often these numbers appear on product labels with spaces or parentheses. However, they should always be entered into the warranty registration form without any spaces or punctuation.
