I am from an older generation and have not lived in castleford since 1971 so can't really help with your particular query but I have recently been reading a book of short stories set in and around Castleford in the 1960s by a contemporary of mine from CGS. As an aspiring author you might find his book interesting as background reading if you have not already read it. It is "More Than I Can Say" by Colin Bellwood. It is currently only on Amazon but enquiring about it on Book Depository may help to persuade them to stock it.
