Vintage light blue gray HARKERWARE gravy bowl and sugar bowl w/o top

Vintage light gray blue HARKERWARE gravy, boat and sugar bowl without top. The gravy bowl has a small chip. I am pointing to it in one of the pictures otherwise in great condition the sugar bowl does not have a lid And does have some dirty area inside. I was not sure how to clean so I didn’t try. Very good condition. 1798.
