Vintage Crown Ducal Ware England "Tulip" Pattern 6 inch Saucers ,Set of 5

Set of 5 very pretty vintage Crown Ducal Ware England Tulip patterned saucers. They feature an elegant floral tulip pattern and a pretty yellow, orange and blue pattern around the rim. The back of each plate is stamped with Crown Ducal Ware England U.S.A Pat. 72944 Reg. No. 732597 There are other little markings on the back of the plates, maybe numbers or stamps, I don't really know.  Measures 6 inches across.  Pre-owned with signs of wear but still pretty. One saucer has some slight cracks on the back and front, as well as a stain of some sort on the back. I decided to also include it as a 5th in the set because maybe it will come in handy. There's also another saucer with slight cracks in the center.  See photos and video for details.
