Can anyone help me identify the maker and date of manufacture of this posy bowl? It's 37.5 cm long, 5.8 cm at the widest point, 4.3 cm high in the middle, and about 5.2 cm high at the pointed ends. In other words it curves up at the ends. The ribbing is on the sides and base. It's smooth inside. There are small roundels along the top rim. There are no marker's marks or registration marks that I can see.
Any assistance is appreciated. Thanks.
Anton
