Ah, the lowly Armstrong DP-1. Even beginners turn their noses up at this poor example of an insulator. But wait! take a look at this one. No, it hasn't been nuked! It actaully does have a unique smokey green color. It really will hold its own in a color display. This really good looking (but very common) insulator can be on your insulator shelf for $10 plus actual shipping cost.
