Whitall Tatum with a number 512U, on the other side it says Made in USA and 6-46 below that a capital A with a circle and two dots. Please with the CD number on this one also, I believe it is a rootbeer amber in color. Thanks for any help my email is wespoetry@hotmail.com I bought these from a 85 year old man today he used to work for a telephone company many years ago. He said a friend took the rootbeer colored one off a line somewhere in Iowa years ago. Thanks again my name is Wesley Willis
