A very cool variant on the common CD 128. I'm classifying this as No name EIN 020, yet this does have a discernable Pyrex blot out. Made in USA also partially blotted out.

VNM save for a couple tiny fleabites. The zinc thimble shows some signs of corrosion as well.

I'm asking $30 plus shipping on this and prefer PayPal friends/family. Thanks for looking.
