Army Industry Factory Soldier War WW1 Machine Gun 2x Postcard s

zx720 Two antique WW1 military postcards  The first is real photo and the soldiers appear to be demonstrating machines they are working on (is this linked to artillery production?) - small or light corner places to allow and perhaps lightly age faded otherwise mostly great condition - The second is British troops in battle with an English Machine Giun showing shooting into the sea from land - a little aged and slight corner edge fraying very mild overall very good plus unused condition.
