I don't know I'll have to ask him but I know we demo tested 1 coin first that worked then I got a message from him saying he sent the rest of his coins and he never got them and the wallet is in maintenance but I'll double check with him. Thanks mate

Also confirm his walletaddress on the blockchain:
