Seem to have missed this topic recently.
Yes, staringowl, Haig was one of the pits I worked in in over 40+ years in mines. The "rags" were the old clothes (sequence = best, casual ,garden, pit) we wore before NCB decked us out in those glorious orange uniforms in the 70s. ::)
Re "The Cumberland Story". The theme was actually the development of Solway Colliery, driving under the flooded workings of Chapel Bank Colliery to reach the Main Band seaward of them. The inrush occurred at Lady Pit on 28th July 1837 (holed into sea-bed about 400yds offshore of Salterbeck Cemetery) and quickly flooded that pit and the connected Isabella and Union pits leading to the loss of 27 lives. (Of more concern to the owners was the loss of 28 horses and all three pits).
Some pit top scenes were filmed at Lowca (Harrington No 10) and some "underground" ones in the training gallery at Siddick (St Helens No 3). The scene where the man runs into the pub to tell of meeting the Main Band was, I was told, shot in "Minnie's" - the George IV in Stanley Street, but that was never confirmed.
There are still Skellys around Whitehaven but I don't know which ones would be related to those who lived at Saltom. Again, there are contacts at Haig who might know better.(I'm not a jameater - I only worked there). 😉
