Franks of Western Expresses : M.C. Nathan
This book has been the standard reference for Western Franks since it was published but has recently been superseded by the 2020 “The Western Express Companies 1850 -1890” by Oscar Thomas. The new book is much updated, expanded and errors in the Nathan book are corrected. Where discrepancies exist between this 1973 book and the newer publication, that the reader should accept the findings of the newer publication.
