This little CD 120 is embossed B over H. BROOKE`S PAT and on the reverse side AUG 14 1883. The Brooke`s blue color is beautiful but there are a few trouble spots. On the upper wire groove ridge there is a 1/2" bruise, and a small chip around the right side. There are some base chips and a 1 1/4" diagonal skirt crack on the patent date side. All that said, my price of $35 delivered seems fair for this insulator.
