Haven't seen any of these for years, then in the last month have been asked to rip these out on 3 jobs.
Brings back memories of the apprentices job of making up a bell set for the only testing ever done on a job.
Any one else come across some old equipment ?
Any one who has never seen these, they were a cardboard box with 3, 1.5v battery shells inside connected to give 41/2 volts. With handy screw clamp terminals you could use these in loads of places
