The following post 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 telegraph line reached the West Central Coop grain complex, the telegraph lines had only CD 145, CD 145.2 and CD 133 Star insulators. Since I've previously posted pictures of the CD 145 [id=81288459] [id=81291972] and CD 145.2 Star [id=81287883] insulators found in Georgia, I only plan to post a photo of one of the many CD 133 Star insulator found on this line in Iowa. At the time, this CD 133 Star insulator was new to my collection, is a very nice color and this one has a lot of character. Details are as follows:

CD-133 Star - Medium Yellow Green - Bubbles, Leaner, potstones & Straw Marks Provide Character - Measures: 70mm Wide x 92mm Height

I probably walked three or more miles of the telegraph line East of the West Central Coop grain complex toward Ames, Iowa and only found the above "Star" 145, 145.2 and 133 insulators on the line in a rainbow of colors. Since these "Star" insulators are not as old as the early Hemingray's found on other sections of this line, my wife suggests that this section of line might have been a later generation re-build. My wives farm is about 1.5 miles from this line and she knows of two different tornado's that hit this section of flat farm land during her childhood. The first tornado destroyed her school and another destroyed half of her fathers out buildings, but spared their house and main barn.

Note: If the reader of this post has interest or collects "Star" insulators, I would like to point you toward a very nice article on page 31 to 37 of the February 2015 issue of "Crown Jewels" written by Brent Burger on the CD 102 Star blob top. This article is an amazing piece of research and had many colored pictures CD 102 Star insulators.
