Hi Alcwyn Thanks for your comment. Chopper Davies was a haulage engine driver at 6 Bells (he took part in the rescue effort following the disaster) and drew what he saw underground, so I would trust him to get things correct. As I'm working from home at the moment I can't check my manuals, but I think that he's showing a 1960s type 'mother gate' cleared by hand. If you'd like to Email me using
