[time-nuts] Visiting Greenwich

[Dave Brown]

I have a pdf of a POEEJ article on the speaking clock that came into service 
24 July 1936 if anyone is interested. I suspect this predates the one under 
discussion? I also have a two part article on the Mark 2 built in the UK for 
Australia.(mid 1950s)
