Thanks both for the added information!
I also guessed that it wasn't that old. But older than 21th C.
On the flaw/inset they don't exactly correspond IRL in position.
But the top flaw is very close to the top 1/3 part of the inset.
The lower flaws/dents don't correspond at all.
Do you have any theories how a flaw like this occured?
I assume it was after it was manufactured?
