The "one-of-a-kind" CD 150 BARCLAY currently in the collection of Bill and Jill Meier. The only insulator known to be embossed BARCLAY. A CD 147 is shown in an old Stuarts book with BARCLAY embossing but we don't know any more about that. Was it real? Where did it go? Were they guessing it was embossed BARCLAY? We may never know.

This unit was found by Rob Lloyd on a fire alarm system in St. Loius.

One can see the distinctive "stamped" embossing used by Hemingray as well as that typical aqua color. And drip points of course!
