Nice group of David Brooks galvanized iron Insulators. Included is the uncommon unembossed piece believed to have been manufactured before David Brooks obtained his patent update from the original 1864 design used only in trees (and from what I understand was used mostly in Canada). No chips, fractures, or damage to any of the glass inserts which all appear to be colorless. $625 includes shipping and insurance via USPS large flat rate box. Thanks.
