Re: Waterton Canyon "Telecom"

From photos and digging the line from Bailey's to Gunnison, I have got a pretty fair idea how this line was built and what was used where. Original construction used CD 133.4 No Name Hemingray No.3's with the Dec. 19 1871 patent on them. A telegraph line into the South park preceeded the railroad, but these appear to be the earliest insulators used by the DSP&P. The South Park seemed to favor Hemingray glass, while the D&RG liked Brookfield.
I never dug even a shard of an HG Petticoat like you show there. "HG CO" stands for Hemingray Glass Co., and that "Petto" type beehive dates to the 1884-1892 period. The others are much newer ( 1910-1918), the No.16 being a "Toll" style for use on old telephone toll lines - somewhat odd for a RR application.
