Not exactly an expert when it comes to insulators, but have collected/dealt in early glass for 50+ years (mostly bottles). Here's a pretty Dominion-42/CD 154 that shades from yellow amber in the skirt up to more of a honey amber in the dome. There's some subtle streaks/layering in the skirt, but difficult to bring out well in my images. Pretty close to mint as far as insulators go, but we'll call it near mint. I see a little pinpoint prick along the upper wire ridge. I see a couple super shallow flakes along the inner skirts inside edge (probably created when the piece was removed from the mold). Marked, "Dominion-42", on one side of the skirt. You'll find a "D" within a diamond embossed on the backside with a little #9 below. Please look at all images for the best description. Asking $185 plus exact shipping. PayPal "Friends & Family" my preferred form of payment.
