Country of Origin: US
Manufacturer: Corning
This is for a covered Casserole from Corning Ware made in the USA. The stamp is A-1.5-B. It is 1.5 liters which is very close to 1.5 qt. In 12 yrs. of selling Corning Ware I have never seen this pattern before except in the matching Corelle pieces. If you are a collector, this is for you.
