Ah... my mistake.
The W.S. No.1 used a 228 volt HT battery, consisting of 20 8-cell refill batteries (one was a spare) and one and a half of the batteries were used to provide -18 volts for grid bias.
The 240 volt battery was for the W.S. No.11, used a 2-pin connector, and was filled with four of the 60 volt HT batteries.
The WS18 (etc.) Static Battery Box (providing HT, Grid Bias and LT) needed a 5-pin connector and they used a British 5-pin valve socket for the connector.
(It was later fitted with a metal collar to prevent the plug being forced in with the wrong alignment, and damaging the set.)
