Research Note: Waltham Serial Lists designate this run as a Model 1883 Grade "P.S.B." (P.S. Bartlett). However, #3000517 and #3000613 have been verified as being more consistent with the keywind/keyset Model 1877 designation despite being manufactured in an era when the Model 1883 dominated Waltham's 18-Size production. Additionally, while #3000613 is marked "P.S. Bartlett," supporting the factory serial list grade designation, #3000517 is marked "Appleton, Tracy & Co." This indicates the run was a mixed anomaly and exhibits conflicting production when comparing factory records.
