Good catch, sorry everyone.

I am sick & on meds, I'll come back with a clear head when I am well.

Until then;

So here is an elective homework assignment for you, note each of these things;

Date on the original Mylar.

Casting date on the engine.

Final assembly date on the engine.

If those three dates are original to any of the examples, neither of the dates on the engine will be dated after the date on the Mylar.

Hopefully I got it right that time. More chicken soup & rest is on my menu.
