Doug Williams received the NIA award for best exhibit of threadless insulators with his display of items made in Canada. Displayed were insulators used by the Montreal Telegraph Company (1847), the Dominion Telegraph Company (1868), the Toronto, Hamilton & Niagara Electric Telegraph Company (1846), the Grand Trunk Railway & Telegraph (1852), and the Colin's Overland Telegraph (1865).

Doug noted that by 1870 there were 20,000 miles of telegraph wire in service. Most of those lines would have been using threadless insulators.

Two of many highlights from the exhibit are shown below.
