Gringotts: Sirius' Vault & Harry's Inheritance

[Brenda M.]

JKR's Dartboard -- Everyone says it's Harry's birthday but I believe
it is 7-1-3, the secret vault from Gringotts where the Sorcerer's
Stone was kept. I later realized, the sequence mattered. Only 7-1-3
worked, not others.

Odd info that has constantly bothered me -- From Sirius' letter to
Harry:

"I used your name but told them to take the gold from Gringotts
vault number seven hundred and eleven - my own." (PoA, 315. UK)

Am I alone in finding it rather funny how Sirius gave his vault
number to Harry? In the first letter to his godson, after having met
him briefly (which wasn't even all loving/touching, half of it was
spent on misunderstanding/strangling), he tells Harry this. This is
the most-wanted guy on a run by the way. Why?

Then it occurred to me -- his inheritance! Harry's name must be on
the safe-list in case of emergency. Harry can take out Sirius' gold
without approval. Which means Harry has full access to the vault,
and now that Sirius is dead *hiccup* it's all his.

I don't necessarily believe the Grimmauld Place will become Harry's
property, let alone that Kreacher, but I think Grigotts vault is
definitely his.

Another thing -- assuming the vaults in Gringotts are arranged
numerically, Sirius' vault (711) must be near the secret one (713),
in fact very close.

-----------------------------------------------------
They were going even deeper now and gathering speed. The air became
colder and colder as they hurtled round tight corners. They went
rattling over an underground ravine and Harry leant over the side to
try and see what was down at the dark bottom but Hagrid groaned and
pulled him back by the scruff of his neck.

Vault seven hundred and thirteen had no keyhole.

'Stand back,' said Griphook importantly. He stroked the door gently
with one of his long fingers and it simply melted away.

'If anyone but a Gringotts goblin tried that, they'd be sucked
through the door and trapped in there,' said Griphook.

Could Sirius' vault be one of these top-security ones as well?

Any thoughts?
