Catalog number was for both items. 4016-21 and 4016-22 may have been for each item.The saucer I have doesn’t have the ray in the center, making it different than any other plate. It is also a different size than the listed 5 plates made. As this is obviously not the Indiana Glass saucer, and with the inclusion of the foot, I’m assuming it is US Glass saucer for now.
