Drinking water container. The ceramic jugs were carried in rescue vehicles in a fitted wicker basket, presumeably for the use of both the crew and any rescued persons in need of water. The writing on the side saying 'Drinking Water' is faded but still readable. Scarce item, haven't seen another. Photos how actual item. Postage is bit high it might seem but that is because it will need careful packaging to defend against the usual handling by couriers, if possible collection would be preferred.
