Two Brown's Pony insulators: CD 187 on the left with the thin glass slug still intact; CD 188 on the right with the raised solid glass plug still intact. The slugs and plugs were a part of the molding process, but had to be removed prior to usage. Not many unpunched Brown's Ponies exist. The CD 188 pictured here is thought to be one of only two known. Both specimens were found at the Brookfield dump site.
