Vintage Walter White Bear hallmark turquoise bolo with turquoise tail ends

Magnificent Inherited vintage native bolo that has sterling silver imprinted on the backs of the three turquoise parts. Hallmark imprint as shown in the photo, Walter White Bear with a bear silhouette in the center, located under the clamp for the black braided leather cords. Per other internet examples, possibly early 70's. Main stone is on the greenish side of blue, almost 1-3/4” tall, almost 1” wide. Black veining/matrix. A bit of exposed matrix surface disruption across the stone at the bottom third, otherwise quite smooth to the touch. See the lightened photo to demonstrate. The large part has 18 total turquoise stones, with individual variations in color and veining, and the outer metal balls are gold color; total height 2-1/2”, total width 1-3/4”. The round tail ends each have 10 total turquoise stones, color variations, 1” total diameter.
