Lessing Serial Number Chart
Our archive holds 12 Lessing entries covering 1900 to 1927, spanning serial numbers 23,090 to 196,000.
Each row gives the first serial number of that year, so a number falling between two rows belongs to the earlier one. Where a chart skips years, the range covered is shown instead of a single year.
