This post starts a series of posts on CD 132 early Hemingray No. 2 telegraph bullets that were found between 1973 and 1975 on the Chicago Northwestern Railroad as it ran West out of Boone, Iowa and crossed the Des Moines River toward Ogden, Iowa. Probably 15 to 20 CD 132 No. 2 bullets were found in colors including: light SCA, sapphire blue, sage green, lime green and various shades of aqua blue. The first post shows the light SCA bullet - this was a one of a kind find and is one of my favorite insulators. Details are as follows:

CD-132 Patent /Dec.19-1871 (Front Dome) - Large Script 2 (Back Dome - No Mold Number) - Light Smokey Grey SCA (Bubbles / Microbubbles) - Measurements: 75 mm Wide x 110 mm Height.

The back of this insulator is shown in the following post: [id=613952171]

It is of interest to note that the topography West of Boone, IA is a valley, river and rolling hills toward Ogden, IA. East of Boone, IA the topography is flat farm land. East of Boone toward Ames, IA there were only CD 133.4 early Hemingray No. 3 bullets used while only the heavier No. 2 bullets were use toward the West.

If you have an interest in the CD 132 "No. 2 Telegraph Insulator", the Glenn Drummond article in Crown Jewels (January 2005) pages 30 to 37 is must reading. This article is very technical and describes six generations of Hemingray production and modifications to the insulator design.
