Base charger for BT Freelance additional cordless handset (Willington DE65)

If you have a BT Freelance cordless phone system with base unit, and want to add an additional handset, this is a charger for the extra handset, to sit in any location round the house. It will only work with BT Freelance handsets. It is not a master base unit. (Extra handsets do appear to be widely available secondhand on eBay, without the charger.)
