Working Code from 1909

46-Year Retired Member Ken Aulbach recently donated this Working Code booklet dated 1909, which was found by his uncle, a Plasterer, in a wall in the 1990's.  It is in pretty amazing condition for its age, and makes for interesting reading. 

All of the pages were carefully scanned and are in order below, but we have included a PDF version if you'd like to save it.
