Good afternoon all.
Lynne and Christine on 20th. Century Pottery have suggested that I post this jug here. I hope someone will be able to ID it for me.
Jug is 19 cm high and 16 cms wide at the widest.
Very difficult to photo the base, but I can tell you that it is very shallowly concave from the outer edge for about 2 cms in towards the middle. This area is "puckered", almost like the skin that forms on paint. (Or the wrinkles around my 50-odd year old lips

)
The centre of the base is more deeply concave and completely smooth.
I have a couple of other pictures if these aren't enough.
Any help greatly appreciated!
