Mixed glaze stoneware owl figurine

Retro 70's owl figurine is made of solid stoneware and appears to be handmade. Unique marking on the underside which is confusing to make out. Looks like a J B or P (?) I had another piece once with the same confusing mark. Measures 3 1/2" tall. All over matte glaze with the exception of the feathers around the eyes, and these have a gloss glaze. Great condiion, no damages.
