Edo period? 3-sided Japanese Sentoku Bronze Vase

3-sided bronze vase, high-relief. I believe this to be sentoku (yellow bronze) with some rubbing to patina and minor scratches, no dents. Looks to have been fashioned from a flat piece of material, then formed into triangle shape. Seam visible on inside with white and green oxidation. Although a pleasing and balanced composition, the workmanship seems a little crude (variations in surface, pitting, inexact detailing).
