Hi Selina i have replied to your message i cant tell you a huge amount about the Bostocks and Calladines, im still researching them myself, my lot where mostly based in whittington moor derbyshire. They would go back there each winter to restock on pottery from the pot factories there and then off they would travel all down the west coast of england to wales selling the wares. Would love to know a lot more about the gypsy earthenware dealers.
