Research Note: #25893 Verified as Two-Tone. #25892 Reported as Two-Tone. According to Hamilton ledgers, #25,850-25,865 were purchased by C.H. Knight & Co. and 25,866-25,900 were not finished/sold until two years later while the rest of the remaining movements in the run were finished and sold. This indicates that 25,850-25,900 may feature a two-tone finish while the rest are standard nickel.
