Blue Delfts Tile

Blue Delfts tile 6X6 inches. It’s a blue and white tile with a image of ships and a tradional windmill in the background. It’s marked Blue Delfts, made in Holland with an image that I can’t found any information on. On the rear of the tile in circles are a G in one circle and the other has 224 and 9 - 2 - 3 . Any help dating this tile would be great. Thanks for looking.
