Working order Keyboard (Hampton Hill TW12)

Hello! I’m looking for a keyboard for my teenage son, he thought himself how to play an old upright piano we used to have when he was 6/7 years old and he used to compose music on it then we sent him to get some lessons and he stopped playing it completely. He now is looking for a keyboard to play again but he is a student and has limited money so if someone has a keyboard that hasn’t been used and would like to donate it, that will wonderful. Thanks.
