Large glazed mottle patterned pottery bowl. Candyware?

Hi, this glazed bowl has no id marks. It is glazed all over with the exception of the rim foot.
2.3/4" deep. 9.1/2" dia.

Looks early 20th Century to Art Deco period in style and colours.

perhaps Wescontree (candy ware) or Ricardia

What caught my eye at first was Samuel Weller

but all his work appears to have been marked or signed.

It's a very common shape.

...for the period.
