I'm searching for photos for my dad (David Halliday) and I believe this might be the same man, he died in an accident around this time down the pit, he taught my dad to play the trombone, any info would be greatly received.
14 has some of the facial features of the Halliday family but I can't say with any certainty that it's one of them. Maybe the suggestion of 'Halliday' might jog someone else's memory.
