Yes you do see them now and again, the back to back linking and also the BS951, in fact the old YEB used a clamp that IMHO was inferior to a BS951 but they were common, personally I like to see the the sweated solder bulb that Norweb did although their earthing conductor itself was more like a piece of wet string. As I straddle both areas I`m used to seeing them (When I say straddle I don`t mean me physically - some may say I do though, but I mean my working area is close to the border of the two old Electric Boards as they were called back in the day)
