I'm wondering if the first pic is of a Kitchener volunteer...
No badges, wierd unifom combination...And very ill fitting!
K1 and K2 especially were "issued" all sorts of wierd and wonderful combinations of kit when they first enlkisted as there was little to none available for them, hence the blue emergency uniforms. The trousers could even be civvy ones! The chap at the back is also in civvies...
