A decade or so ago I was tasked with acquiring a WWII-era "Tele F" field telephone or two for a friend, and when one turned up at the Harwell radio-rally, £2 passed between buyer and seller, and it was mine.

Taking the lid off revealed the two square brown-wax-paper-cased 1.5V cells with a somewhat-tarnished brass screw-terminal atop each.

They were made for the MoD by 'Crompton Vidor ' and dated 1969. Though they showed zero terminal-volts they also showed no sign of any leakage.

Not bad for 35-years-old cells! [The Tele-F's cleaned up nicely too, and with a couple of D-cells-in-a-holder fitted to each they gave good communications over a mile or two of D10]
