2nd photo, Mk1 gun with Mk2 butt. Note the bino case above the webbing, to the right of the carrying handle and extreme left hand bottom corner, one of the old what we used to call 'tea-bombs'. Last seen by me in the late 60's or so (but probably went on until later I suspect.....) used for taking hot food/tea up to the blokes. Replaced with better 'norwegians' and then something else
Bottom photo. They wouldn't be in that trench if the 17 pounder opened up! More No2 binos again. The bloke standing up has on a 'jerkin, leather, drivers' Great bits of kit. Thick, supple leather, sleeveless, lined with a khaki blanket like material. Last saw one in 1963 or so when the RASC drivers all seemed to have them
