This lid has held my eye since I first spotted it in a collection I picked up this week. I suspect it is a lid to a Ramsey jar, it matches the written description, and it sort of looks like the line drawing in my copy of Redbook, but there is a difference. The line drawing shows a center post on the lid, whereas my example is just recessed. Round on the top, oval on the underside/bottom, with protruding wings/lugs as if to engage lugs in the jar neck. Looks very easy to break if you ask me.
