Insulator on right is a nice Hemingray - Back No. 50, and appears to be mint but will say VNM. Comes in a nice blue color, The insulator on right is also a CD 190/191 and comes in aqua.. It's embossed on front A.M. Tel & Tel. Co.- on back two piece transposition. One spot on top has a little roughness, small flake on base on top piece and inside where threads begin a little roughness. A lot better than described. I'm asking $40 for both lplus actual postage.
