Possibly an '86?

Does it look 23 years old?



AO Smith - Can be confusing; digits may be comprised of letters & numbers. May be one, two, or no letters.
If two letters first, next two numbers are year.
If one letter first, followed by two numbers and another letter, next two numbers are year.
If one letter first, next two numbers are year, providing no letter follows.
If two numbers first, this is year.

February '79 is what I come up with. B-Feb, 79 year.
