Hi,
The second uniform looks very similar to my wife's Gt-Grandfathers uniform.
He was a bugle boy, and joined the Durham R & A (Whatever that regiment is) in 1904 aged 14.
His uncle bought him out of the army for £1.
He was re-called up in WWI and served with the KOYLI (King's Own Yorkshire Light Infantry).
I don't know if that uniform was the same for Bugle Boy's in all regiments, or just the Durham R & A.
Thanks,
Darin.
