Default Re: F. Stephen Masek's Bush SAC21 restoration

The plug was probably BS546, a 1934 British standard which was largely superseded by BS1363 from the 1950s onwards. It is rarely seen in Britain today apart from in lighting setups in theatres, but it remains a current standard in places like India and South Africa.
