Det var mycket tydligt från den sista boken att Cloaken som Harry hade, var den ursprungliga Invisibility Cloak och Hallowsna existerar.
“The Hallows, the Hallows,” murmured Dumbledore. “A desperate man’s
dream!”
“But they’re real!”
“Real, and dangerous, and a lure for fools,” said Dumbledore.
“So it’s true?” asked Harry. “All of it? The Peverell brothers—”
“—were the three brothers of the tale,” said Dumbledore, nodding.

You have guessed, I know, why the Cloak was in my possession on the
night your parents died. James had showed it to me just a few days
previously. It explained so much of his undetected wrong-doing at
school! I could hardly believe what I was seeing. I asked to borrow
it, to examine it. I had long since given up my dream of uniting the
Hallows, but I could not resist, could not help taking a closer look .
. . It was a Cloak the likes of which I had never seen, immensely
old, perfect in every respect.
Deathly Hallows, Ch 35: King's Cross
Xenophilius gjorde det också mycket tydligt när Trio går för att träffa honom att det finns Invisibility Cloaks tillgängliga på marknaden men det finns bara en "sann" Hallow.
“Ah, but the Third Hallows is true Cloak of Invisibility, Miss
Granger! I mean to say, it is not a traveling cloak imbued with a
Disillusionment Charm, or carrying a Bedazzling Hex or else woven from
Demiguise hair, which will hide one initially but fade with the years
until it turns opaque. We are talking about a cloak that really and
truly renders the wearer completely invisible, and endures eternally,
giving constant and impenetrable concealment, no matter what spells
are cast at it. How many cloaks have you ever seen like that, Miss
Granger?”
Deathly Hallows, Ch 21, The Tale of Three Brothers
Så jag antar att den Cloak som Moody innehar var en som var charmad eller gjord av ett speciellt material. Det faktum att sådana klockor existerade var inte riktigt nyheter.
