[Station X]

ISTR there was an earlier drop wire coloured black. Possibly it was terminated on an old style protector. Or may be 2 core flat cable was run from the drop wire to the protector. If so I don't know how the connection was made, perhaps inside an old style insulator? The whole idea of drop wire was to get rid of insulators etc. The drop wire was mechanically terminated at the pole and premises using clamps. The later ones were coarse helixes of insulated steel wire which the drop wire was wound around. The earlier versions had some kind of sliding clamp.
