Delft blue and white 2 cup teapot

Pretty delft teapot is small and has 2c on the bottom which I'm assuming means 2 cups. Pretty cobalt blue floral decoration on white, all underglaze. Marking on the bottom is odd and I can't understand it. It's a pie slice shape with unlegile markings. also stamped 3P.15K. Great condition, and measures6" to the top of the lid's finial. Not sure of age or company who made it. Need photos of bottom stamp just email me.
