Interesting tri-legged stoneware fish mold for food.  Glazed interior with unglazed edges and bottom.  I am not sure where it originated or what time period, but its appearance suggested age.

Size:  17" long by 6 3/8" wide by 3.5" tall.

In very good condition overall.  Some small chippiness to glaze on edges, but no cracks or chips to mold.   Examine all photos and use enlarging feature.
