I'm not sure of the color, but I'm thinking maybe powder blue. The one on the right has a 10 embossed on top. The one on the right has a 16 embossed on top along with a backwards 16 side by side upper and lower. I found these this evening had to climb high to reach both of these on seperate poles. One of them after I reached lower cross arm still had to stand on my tip toes to reach it. I noticed the line running all the way over the tops of these CREB's I was told that means a two piece mold making it around the years of 1880 to 1890.
