Cryor, President North American Asbestos Corporation 200 South Michigan Avenue Chicago, Illlnoia 60604 f-.' ^ ' Dear Mr. Cryor: Under separate cover I an sending you several samples of Aaoslte Fibers forwarded from our Tyler, Texas plant. Their basie cmnplairxon this material involves a question of proper grading of the fibers that have been received in the most recent shipments. Our Works Manager, Mr. C. E. van Horne, told me that he does not feel that the Amoalte he is receiving should be classified as Grade Dll material. The color ranges from grey to blue and the darker fibers are extremely dusty. The dusty fibers are creating problems in the produc tion of UNIBESTOS. We reviewed this problem briefly with Dr. Gaze on the 10th and be suggested that we send these samples to you for inspection. We would appreciate it if you would examine this material and give us your opinion as to the quality of the fibers. Best wishes for s Merry Christmas and a Happy Rev Tear! Tours very truly, ~ Guy P.
