More About Star Glass Works

   by Jack Roberts

   

I wrote you about six weeks ago about the Star Glass Co. When I wrote you I also wrote New Albany. You sent me your copies of C. J.'s and information that is contradictory to the information of the past. I think we glass collectors are faced with living without the true facts of the "star" ...                    [more]



   

Montana's Power Insulators

   by Marv & Vicki Miller

   

I'm writing this in hopes of answering some of the questions asked about Montana's power insulators. Montana is best noted for its Muncies, Coolies and Stackers.

CD311-Cochrane Purple Montana Stackers

CD133-Hemingray in Amber

   

   

Dear Dora,

Just received my April "Crown Jewels". In your research section you got a letter from Ken Herring stating he had a Hemingray #20 amber. Your reply to him was that you thought it was a cobalt treatment.

I have two of the Hemingray 20 ambers for sale. They are not fake, and seem to be ...                    [more]



   

Info On Patents

   by George F. Lahm

   

I have been wanting to write for quite a while, but just haven't had the time. Winter was late in arriving, and, since I work for a highway department, this has been keeping me busy, especially since February 1.

I have been looking up Patent information on insulators at Cornell University when I ...                    [more]



   

C S Knowles

   by George F. Lahm

   

The main patent that I wanted you to have is the Knowles trademark. When I saw it in the Patent Records, I was hoping it would turn out to be the Prism, now the Emerald. There was no drawing in the book, only the mention of it being patented.
