BURLEIGH WARE GOLFER

Golfer Jug. This piece has an unusual backstamp. It is marked "Burleigh Ironstone Staffordshire England". It is very heavy (about twice the weight of a normal Golfer Jug). It also has a very feint impresed mark ETB (?).I am sure some Collectors out there may be able to throw some light on the piece and i would welcome their comments
