Vintage Watt Pottery American Red Bud Tear Drop Flowers #15 Small Pitcher 5.25"

This is a vintage Watt Pottery #15 pitcher. According to my research, I'm pretty sure this is an authentic piece and not a reproduction. The attached handle did not make an indentation in the interior. It is over 5" tall to the spout (at 5.25", almost 5.5"). The brush strokes and colors on the painted design also seem proper. If anyone has any info otherwise, please let me know. :) The design on this piece is the American Red Bud or "Tear Drop." I have found one small area where the exterior glaze has a crackle. There is also a tiny chip along the upper rim. This is shown close up in the final 2 photos. Please see all photos for conditioning details.
