Gulbransen Serial Number Chart
Our archive holds 18 Gulbransen entries covering 1915 to 1969, spanning serial numbers 90,000 to 583,000.
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.
