No. 429 Sent to Mrs. Eliza Hamand in Somerset, Ohio. Taken by Jones and Russell’s Pike’s Peak Express Company, which bought Leavenworth Pikes Peak Express, the first express between Leavenworth and Denver. Its first trip was on May 28, 1859, and it failed one month later. Jones and Russell only lasted four months, failed, and were taken over by the Central Overland California and Pikes Peak Express (COC and PPE), which later operated the Pony Express. The COC and PPE also ran into trouble, and depended on Wells Fargo to operate the western half of the Pony Express in 1861.
