Dialatron Caprice 12B corded telephone, no power needed, works fine including during power cuts.
(Bought from Tandy in Chesham in 1996 so the warranty has definitely expired!)
Kept for backup, power cuts and testing during broadband problems. Tone or pulse dialling!
As we're now on fibre broadband and digital phone service it's no longer required.
Note that the cradle has minor damage and can no longer be wall mounted.
