I recently saw this colourised picture on Twitter... It's described as having been near to Tilly-sur-Seulles... And I wondered - haphazardly if the Tac square might have been originally "yellow" There seems to be a 52 on one tank and a 54 on another. Not sure if this picture is well known? I'd expect it to be. It's a pity that it was not originally better described and referenced but I'd still like to figure out what I can about it if anything is currently known? All the best, Rm.
