The company of José Oriol Escardibul was founded in 1840 in Barcelona and started as a famous producer of Billiard equipment. In the 1920's, under the management of Eusebio Escardibul, the company expanded its products inter alia to chess and over the years became one of the famous Spanish chess set manufacturers with the crude Knight carvings being one of their trademarks. It doesn't get more Spanish than this!
