Thank you for your question on the B&L vase. Hi, my name is Ray and as one of the Just Answer experts it will be my pleasure to help you with your question. As I am sure you already know, Burgess & Leigh was a very old firm which occupied the Central Pottery, Burslem from 1862 to 1867 ( probably as Burgess Leigh & Co). In 1867 B&L took the earthenware department of the Hill Pottery and then in 1899 moved to the Middleport Works which were purposely built for them. Years later, in August of 1999, the company was renamed Burgess, Dorling & Leigh following a financial crisis. You mentioned the 'beehive' which was a mark used beginning in 1862. A beehive surrounded by leaves identifies the item as pre-1940 - after 1940 the beehive no longer had leaves. The 'Burslew' you mentioned is actually 'Burslem'. Is this info so far so good before I get to the valuation?
