This larger shard is from J & G Meakin. That is J & G for James and George, the sons of their father James Meakin.

"Manufacturer of earthenware at the Eagle Pottery (1859-1970) and the Eastwood Works (1887-1958), Hanley. Brothers James and George Meakin took over the pottery manufacturing business of their father James Meakin in 1851, operating at Cannon St, Hanley. James Meakin junior died in 1885 and George Meakin in 1891, but the family business (incorporated as J. & G. Meakin Ltd in 1890) continued first under George Eliot Meakin (son of George Meakin), from 1891 to 1927 and then under Bernard Meakin (son of George’s brother James) from 1927 until his retirement in 1955." From what I have read the family sold the company but it continues. Visit: www.potteryhistories
Also look for free at pottery-marks at books.google.com. Search for: Book of Pottery Marks by W. Percival Jervis, written in 1897. It is excellent should you come across a old shard. The book is digitized from the Harvard College Library. Many people online (at sites) do not give Mr. Jervis credit for a job well done in 1897.
