Here is a CD 134 No Embossing Oakman style. I can't tell if it's EIN [040] [No embossing] {Oakman mold; diamond plunger mark in the pinhole} SB or [045] [No embossing] {Oakman style; Pennycuick threads} SB or [050] [No embossing] {Oakman style; comes with and without a small diamond shape on the dome} SB. I don't believe these are Pennycuick threads, though. So that leaves [040] or [050]. I can't distinguish these on this insulator because there's no diamond shape on the dome, and there is a HUGE bubble that takes up most of the dome [id=398394692] and is open to the top of the pinhole where the plunger mark would normally be. [id=398394862] In fact, it appears that at some point in its life, there was a small spider living in the open dome bubble because that stuff looks like cobwebs inside the bubble. I believe this signal was made at the Lyndeborough, NH, glass plant based on the clear embossed vertical bar on the inside of the skirt which I understand to be one of the defining characteristics of that manufacturer.

I'm not sure any of the Price Guide listings describes this particular insulator. While it will look very nice on my shelf with other unembossed America/Oakman insulators, I will clean it first. Before I do, does anyone here want it for $150 shipped before it goes in the bath? Thanks for looking.
