I picked up this Hemingray CD 145[070] at a junk shop the other day because of its different profile compared to other CD 145s. Shown in the picture for comparison are a SDP Hemi beehive, and a SB hemi beehive. My question centers around the steeper angle of the sides on this RDP Hemi beehive. Is this a common shape for all the Hemi21s or just the RDP. I don't have many of this type to compare with so if any of you Hemi experts want to chime in would be great to hear your opinions ********************************************************************** From several of our resident experts I learned that this particular style of Beehive was one of the last introduced into the market. This narrow style is only found on the RDP version embossing index[070] &[090] For those of you wondering about the color it is a very blue Hemi Blue
