Shouldn't be too hard to find gold in London, there's 7,500 tonnes stored there, 3/4 of it custodial gold at the Bank of England.

The Bank of England also offers a custodian service (gold only). In total it is estimated that there are approximately 7,500 tonnes of gold held in London vaults, of which about three quarters is stored in the Bank of England.
