In 1975 I completed graduate school (University of Iowa), found a job, and moved to Haverford, Pennsylvania. I previously reported that my mother found an orange amber CD 729 [id=609421506] and two CD 732 threadless insulators [id=609422281] [id=609422587] on the Northern Central RR telegraph line South of New Freedom in York Co. Pennsylvania. My family and I would visit my grandparents near New Freedom, PA three or four times a year and I had an opportunity to hunt for threadless insulators. In 1978, I was lucky and found CD 729 threadless insulator. Details are as follows:

CD-729 No Embossing - MLOD / Button Mold - Blue Aqua - Measurements: 75 mm Wide x 97 mm High.

In the late 1960's, the Northern Central RR and the New York Central RR merged with the Pennsylvania Railroad to become the Penn Central Transportation Company. In the early 1970's the Penn Central RR went backrupt and joined CONRAIL in 1976. The Northern Central RR was abandoned in 1976. During it's years of operation, the Northern Central has two tracks through the New Freedom, PA area. The railroad line ran North - South and the telegraph line in the 1960's and 1970's was on the West side of the tracks. The threadless insulators that my mother and I found were all on the East side of the tracks suggesting that the earliest telegraph line was on East side of the tracks. The poles on the existing telegraph line had two cross-arms. The insulators on the standing telegraph line were all common suggesting this was second or possibly third generation. I should also note that the threadless insulators that were found had very little soot suggesting that the threadless insulators were only used for a few years.
