No, I'm afraid that is not the Sara lather bowl. For one thing, the Sara lather bowl does not come in that color. Also, this one seems to be more tapered toward the bottom than the Sara bowl. Finally, it looks a bit smaller.
Ray is right, and you my dear Obie, are wrong. It is indeed the celebrated Sara's lather bowl. Also known on the Canadian side as the Ayer's lather bowl.
