Here is another addition to my collection of rare pieces, a CD 186.2 Hemingray 19 signal. These are extremely bizarre insulators having a lead lined pinhole and for reasons completely unknown to me, a large 6 sided hex nut in the dome with an opening. Maybe they would screw some type of connector into this machine threaded hex nut? If anyone has any other info to share on this, I would love to know please. Not perfect, but whole nonetheless. Has a large crack on the rear skirt and around the midriff of the dome.
