Old style telephone (Prickwillow CB7)

Beige coloured old style telephone for land-line, plugs into phone line directly. In working order but doesn't work if your phone line comes via the Internet. Was kept for use during a power cut as you can still make calls with no electricity but no use now the phone line has been changed to come via the router. Any use to anyone as a phone or as a prop for a play?
For collection from prickwillow evenings and weekends or Cambridge science park during working hours.
