I wonder if anyone on here can help? I'm trying to find out more about my Grandfather, Albert Edward Stevens from Poplar in London, who served in France and Belgium during WWI and as a fireman in the London docks in WWII. This is the only photograph we have of him from WW1 - he's third on the right, top row, with the moustache. Not many clues in the picture but does anyone recognise the cap badge of the guy in the middle of the bottom row? Would really appreciate any information or advice - is there a particular regiment or unit he would more likely have joined from the East End of London? All advice gratefully received, thanks in advance.
