The photographs are not credited at the request of the photographer to whom I would like to say thankyou! (you know who you are :) )
The first 3 shots show the the 504 face cutting coal, by 10:28 it was all over.
The second set of 3 pictures show coal being delivered from Face to surface Bunker, then Coal just in the surface Bunker, then No coal at all! Bunker empty!
