ANS signed “Edison,” one page, 8.25 x 10.5, August 23, 1921. Note at the top of a letter written to him, in full: "Luhr=Go ahead and make the change if you have none of the old ones or not many in stock." The main letter, by Charles William Luhr and addressed to "Mr. Edison," reads: "Disc feed rack of thicker stock is very much better and more mechanical. It will cost 44¢ per 100, more in material nothing additional in labor no change in tools, would suggest that we adopt standard U.S. gauge size #14 (.078″). Model is .080″. Soft cold rolled steel. We will try and use the annealed sheets instead of bright finish, cold rolled steel, this works just as well and much cheaper. We can then also save nickel plating it." In very good condition, with tears and chips to the edges of the rather fragile sheet. Charles William Luhr worked for Edison for more than forty years, specifically assisting in his work with the phonograph and stock ticker machines.
