Notice wire groove and upper edge of wire groove difference. The Brookfield on the left has a sharp edge and the wire groove is distinctly different. How can the Brookfield be a CD 162? But that is as near as I can get in the ID guide.

Also notice the nipple on dome of the Brookfield [id=268769895]

And see the Brookfield compared to another Hemi 19 [id=268768464]
