So whether the disk was made last week or a hundred years ago is irrelevant. It is not original.
And please note, this conclusion does not require any esoteric knowledge of unit markings. It is a simple case of wear and tear not matching up.
I apologize if this becomes a little bit of a lecture, but time and again posters get entangled with questions of markings, without looking to see if the components match in wear and tear.
Look at what you see!
