I am a bit late to this post but Jebber is correct.
The Jarrow marchers were in extreme poverty, many miners ,many W.W.1veterans who were literally starving and so too their families .
It was an attempt to highlight the disgraceful neglect of WW1 soldiers who had returned home to extreme poverty and no work.
Especially in the N,E, but they were joined by others as they marched down to London to confront the government as their war service and poverty counted for nothing .

I agree it's something ex military.

I think the 2 men at the front carrying overcoats were perhaps officers and they were the only ones who could have afforded overcoats, so maybe autumn/winter .

  I also thought the men at the front were officers, especially the one in the bowler.
