I have on offer a PANASONIC EASA-PHONE Tone Remote Controller, Model no. KX-A74. I bought it a long time ago in the days before mobile phones to access my answering machine and retrieve my messages at home when I was away. It is still in excellent working order with a working battery. I realise no one is likely to need such a device now and I may well have to throw it away but I thought I would offer it just in case.
