Here's a group of BROOKFIELD 164s, out of these pictured what one do you consider to look the most like a 164 ???. I guess the point of this is just because until you really study a single CD, you don't realize how many variations within a CD . Also to make different variations you include other molds acquired and retooled makes for an interesting group. And when you think you have found all of them, you come across yet another variation .
