Easy peasy, have a look at Fionn Taylors website on mines rescue and a bit more, google healey hero. That should point you in the right direction. On the front page click on Bob Bradley. That will take you to Bob's history of East Midland coal mining, blinky flip there is a lot to get through. If you start at the year Bestwood opened and carry on to the year Bestwood closed. Best viewed with a plate of sandwichs and a flask of coffee, it will take that long. Apologies for any spelling or grammar errors, I only started being a pensioner in February
