old adobe brown stoneware pottery kitchen mixing bowls, vintage Monmouth?

Two vintage stoneware bowls marked USA, vintage Monmouth pottery, we think? These are 6" and 9" in diameter (3 1/4" and 4 1/2" deep), both with the same ribbed pattern, glazed in different shades of adobe brown and tan over a pale yellow ware pottery.

Both are in very nice condition without damage or wear - it's a piece short of a complete nest, but these good old stoneware pieces are getting hard to find!
