CUEVAS. Accion. Serie 1. blue. No 2307. Formed 1880 to bring a supply of drinking-water to the town of Cuevas. But there are many towns in Spain (and other Spanish-speaking countries) named Cuevas, and we cannot be sure which one, in this case. Our guess is the well-known mining town of Cuevas, in the Sierra inland from Cartagena.
