nie looking original instruction book for Maxwell serial 476040 and up $75. 608-873-9521 afternoons

I have 1918 first edition Maxwell Instruction Book. I'm not sure about the serial number. The book is in good shape considering it's 90 years old and looks like the owner used it! The corners are bent and there are smudges on some of the pages. The book itself is still complete with no torn or missing pages.
