I have received permission from
Direction Interrégionale de la Mer Nord Atlantique-Manche Ouest to publish the photograph on this forum. All photographs are copyright © DIRM NAMO
From the email: "vous pouvez utiliser nos photos à partir du moment où vous indiquer le copyright suivant: © DIRM NAMO "
The person who has supplied these will look for info on La Tourelle du Chat at the beginning of next week. They have emailed a photo of Le Chat taken in 1935 but I think I will wait for more info before publishing here as it looks somewhat different to La Tourelle du Chat of today - still with 2 platforms but somewhat thinner. The internet seems rather sparse on info re this one.
The photo of La Tourelle de La Plate is from 1936.
