In 1971, the Columbus, Ohio Chapter of the Telephone Pioneers of America, a charitable association of telephone company veteran employees, undertook a large fund-raising project.

In commemoration of the 60th Anniversary of the founding of the Telephone Pioneers, they made three identical insulator molds, similar to the CD 735 Chester U.S. Tel. Co. design, and produced a large number of private issue insulators, for sale in eight colors. These were made by the Imperial Glass Corp. of Bellaire, Ohio. They were offered for sale in 1972 for $3.75 each. (Note: $3.00 was set as the minimum price to be charged per "Sales and Ordering Information" on previous page.) 

While there were eight base colors, changes in glass batches produced a changed shade in azalea (to lilac) and in the greens (the first run being blackglass; the second, third and fourth being shades of emerald or forest green; and the fifth being Metropolitan green, nearly teal green). The crystal clear pieces were intended to be distributed only to Columbus Chapter members.

There are also a handful of patterns. Approximately ten were produced in citrine to test the molds, and about four of these were then carnivalized orange. None of the patterns were embossed with the Imperial Glass Co. logo on the dome. 

The total production resulted in a staggering 24,447 pieces for sale, and the resulting sale produced some outstanding fund-raising for the Ohio School for the Deaf, among other projects. The wood pattern was turned by Bill Hunt and the other prime forces behind the project were Pete Bishop, Joe Frederick and Lynn Georgia. All three of the molds are still in existence.
