Here is the other mold variant of the Hemingray CD 154 I was finally able to get. This piece has small sharp drip points and a thick upper wire ridge. Another feature that makes this variant different is that both wire ridges are of the same size, unusual because in all other Hemingray CD 154 insulators the upper wire ridge is smaller than the lower wire ridge. A really cool piece that reminds me of some short mold style Columbian Zicme CD 154 with the thick glass on the upper wire ridge.
