The following series of posts show some of the more interesting insulators that were found on the Chicago Northwestern Railroad as it ran East out of Boone, Iowa. East of Boone, Iowa the major railroad towns included: Ames, Nevada, Colo, State Center, Marshalltown, Montour, Tama, Belle Plaine, Blairstown, Watkins, Norway, Fairfax, Cedar Rapids, Mount Vernon, etc. In the sections East between Boone and Ames, Iowa, I have previously posted on CD 133.1 and CD 133.4 early Hemingray telegraph insulators which were found very near Boone, IA. As the telegraph line moved 0.25 miles East out of Boone, the more uncommon insulator found included: CD 145 H.G. Co./Petticoat in SCA; CD 145 No Embossing Pennycuick; and CD 151 H.G. Co. /Petticoat in ice /near clear. Once the railroad reached the West Central Coop complex, the telegraph lines had only CD 145, CD 145.2 and CD 133 Star insulators. This post shows the CD 145 H.G. Co. in pink SCA:

CD-145 (Mirror Image "N" Mold Letter) H.G. Co. (Front Skirt) - Petticoat (Back Skirt) Pink SCA - Crude With Large & Micro-Bubbles and Straw Marks - Measures: 82mm Wide x 104mm Height.

A post showing the back of this insulator can be found at [id=618499716]. There were a number of CD 145 H.G. Co. insulators in various shades of aqua to aqua blue, but there were only a few of the pink SCA color beehives between Boone East to the West Central Coop.

I will post a picture of the CD 145 H.G. Co. in pink which compares color with the CD 145 H.G. Co. light lavendar insulators which are found in Georgia [id=618500728] . Someone once told me that the CD 145 H.G. Co. /Petticoat in SCA can be found in 100's of shades of SCA.
