CD 161's: Left is light sage green with black fragments around the embossing. Tough to find any junk in a Cal for some reason and when you do it is a rock or fire brick, so the black stuff is extra nice. Right is a "California Blue" signal just loaded with milk upgrade. The color is very distinctive and for some odd reason didn't get listed in the new guide in all the right places: CD 102 California pony, CD 112 keg style variant, CD 152 taper top variant, CD 160 baby sig, CD 161 sig, and CD 162 sig.
