Guan yao nei zao Imperial Kiln for Inner Palace Antique Porcelain Oblong Bowl

Up for your consideration is this antique oriental porcelain china oblong bowl. The bowl I believe is from the Guan Yao Nei Zao (Imperial Kiln) based on the markings.

It has a wonderful scalloped edge with a beautiful blue leaf with chrysanthemum floral & bird pattern. This boat design with footed base has a spider line crack on one end. Please review last 2 pictures. I see no other cracks or chips. The bowl measures 11 3/8" long x 4" tall x 7 wide.
