w.m still & sons coffee/ tea machine

I've had this machine for a while now, not sure on how many units are still around . I've found bits and pieces on the net , but none in working order . I got this coffee machine by donating to a hospital in the state victoria of Australia . The hospital was permanently closing the ward ,and I know that this was the last one left in the hospital.

Does anyone know anything about this unit ? Let it be dates, value, quantity ?
I would really appreciate some feedback , as resources are very limited .... thanks !
