Ivory pottery vase ridged

Ivory pottery vase with ridges marked b + B on the bottom. This is a Burton and Burton piece. Very nice condition overall. Since this piece is meant to be “chippy” it is hard to determine what’s damage and what’s mean to be. There is one small chip about 5mm that is an actual chip as shown in the photos. There are two other tiny spots that I’m not certain are chips or original to the piece. Please view all photos. Very pretty pottery piece would be perfect in a Farmhouse style, Boho style and many others. 7 1/4” tall 3 1/2” opening 4 1/4” wide
