Sojin Serial Number Chart
Our archive holds 16 Sojin entries covering 1982 to 1990, spanning serial numbers 10,201 to 142,058.
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.
