Start and end production date on authentic retro 11 Concords?

I'm aware that the end production date is different for a lot of authentic ones as you can't produce all of them in one day.. but around what day are authentic ones?

if anyone could post a picture of their size tag of their concords that they got from Footlocker/Champs/a legit shoe store themselves that would be greatly appreciated, thanks.
