J&M P. B. & Co. Large Platter

I found this large platter a few days ago. It was manufactured by J&M P.B. & Co. Glasgow. It also has a mark, JB inside a Bell, it's also stamped granite. It seems to be a really simple pattern for this manufacturer. The pattern appears to be tulips, or some other type of flower. It mesaures approx. 20" x 15". I'm having a hard time finding the name of this pattern and dating this piece, if anyone has any insight, I would love to hear from you!
