Mark is from circa 1930 I believe. Very light wear to gold on handles and a couple tiny white flecks on green. I did quite a bit of research trying to find others like this but the only other I can find is this exact shape, but is a prototype in another color not marked for the infamous retailer. A rather unusual style for Lenox as well in my opinion.
