Received from the (real) Pye Museum:-
'Hello Alan,
Your Pye BT1 unit is a state-of-charge indicator for Pye PMR Pocketfone PF70 series 15 Volt Ni-Cd batteries used in the commercial PF2, PF3 and PF5 series hand portables in the 1970s.
They were also used by the British Army in Northern Ireland etc during the 1970s.
It does a 5 second load test when the button is pressed.
I will dig out the product leaflet and scan it for you later today.

I've asked him if he's got one etc.
