About 1971.
Well before the change from early C/M to late C/M.
But we're not discussing lenses.

Have we not?
Anyway, as you do know, lenses are interchangeable, and a camera that 30+
years later still has the original lens it came with is rather a rarity.
And by the time the 500 C/M changed a bit, all lenses had been T* coated.
In fact, the old lens line that had some single coated lenses earlier had
been replaced by a new line already.
Now you see why we are not discussing when lenses got T* coating?
Of no concern whatsoever when you want to know when a 500 C/M was 'revamp'
a
bit.
