Part of the serial number sequence of lenses made by Ross. Note that the source warns that 'anomalies' exist, and suggests that some lenses, either made by Ross from designs of other companies (such as Zeiss and Goerz), or lenses made for Ross by subcontractors, may have their own serial numbers unrelated to these.[1]
