Group of 4 CD 102 Brookfield insulators and 1 CD 101 with SDP. The CD 101 has some nice amber swirling. There are a few flaked drip points and a small flake on the upper wire ridge. The rest are embossed BROOKFIELD only. The one with the amber swirls has a 00 on the dome top and a cool half moon shaped fold of glass at the right mold line. There is a hard to see crack in the threads that has to be turned a certain way to see otherwise it is invisible. I missed it initially. The remaining 3 have no mold number. Price $10 for the whole lot plus shipping by the cheapest means I can safely ship (likely either Regional or Flat Rate box) I have similar groupings of CD 145s and CD 152s and can do a mix and match for the same price. I can combine this with other lots for additional savings on postage. PayPal welcomed using the Family and Friends no fee option. Other forms of payment fine as well. First email as always where you say you would like to purchase these insulators.
