I believe this pottery is from the late late 19th or early 20th century. If you see photo 1 that is the typical green glazed you see on 18th century pottery and the 2nd picture is of 19th century and the third photo which is more of the style of green glazed you have is more typical for late late 19th and 20th century pottery.
thanks guys, yes I'm finding closer results with the Mexican pottery, green Majolica is to be the closest but yet found my piece. I will continue searching
and hope to find the answer soon....
