This is showing a regular CD 152 Brookfield on the left, and a regular CD 152 Hemingray on the right. In the middle, is what I call the "The Brookfield style" Hemingray. You will note the shape of the dome, the flair of the skirt, is pretty identical to the Brookfield, and significantly different from the other Hemingray. The base diameter of the first two is a little under 3 5/8" and the one on the right is a little over 3 3/4" -- So, they are about 3/16" difference. Not a world of difference, but significant.
