In the May 2005 issue of Crown Jewels, we featured a number of one-of-a-kind insulators from the collection of Butch Haltman. A couple of other collectors have submitted pictures of "one-of-a-kinds" they own.

Paul Ziemer sent us the picture of the CD 1003 glass block pictured on the inside of the front cover of this issue. What makes it unique, he says, is that it was found on a tree with the original mounting bracket. Most frequently, the wood parts for any early telegraph insulator have disintegrated over time.

Paul also sent in the picture of the CD 134 Hemingray-produced signal (below) that is embossed PATENT / DEC. 19, 1871 on the front and PATENT MAY 2 1893 on the reverse. He says it is unique in purple.

Crown Jewels will feature more "ONEOFA's" in upcoming issues.
