THANKS FOR POSTING
That is the earliest dated factory letter I've seen,I have (copies) from Oct. 18 1924, Nov. 18 1925,Nov. 23 1926. The only difference in the letterhead, the pictures are different. So many of the correspondence files were destroyed in the many fires that they had throughout there existence, the worst was in the fall of 1929 just after the sale to Snow Flyer the factory was totally destroyed.
Bob,Your welcome! I thought this scan would be of interest to you.
