I guess the OP has found the address which have 40 BTC and have the last transaction from 2011 and which tells us that the address was not used again since 2k11 and the owner must be from early adopters and lost hi faith in Bitcoins in very early stage and he lost his password/key/wallet etc.
And this user has found the address and wants to transfer the bitcoins to his address without they private key.
OR if he found an address with priv key then he is going to rich :p
