The attached plate is owned by a neighbor. it is damaged and was found in an old stable adjacent to a house that was built in the 1700s.
It is Cobalt Blue and Grey Stoneware with what appears to be a KOI (Carp) design. The back has initials O or D, with an L below it, and also has another design -- mouse or ?? which is hard to discern.
Any insight on maker, age, value, repair costs if feasible, would be welcome.
Trying to help the neighbor obtain some information.
