I thought the viewer might like to see all three of my CD 127 April dates in green shown in one picture. The insulator on the left is a "knob" dome short mould with an April 1871 date. The color is more of a dark mint green. The insulator in the middle is a "mushroom" dome CD 127 April 1870 date in a color I've called light teal green. The insulator on the right is the taller "knob" dome mould variant CD 127 April 1871 in a color that leans more toward a darker lime green. I know everyone sees different greens so call them as you see them - they are all shades of green which both the "knob" and the "mushroom" dome styles represented.
