RN numbers?
- Thread starter CaptMicha
- Start date
The RN search is here

but that won’t help you date directly. There is a formula you can use loosely to establish the earliest it could be from but that doesn’t mean it wasn’t done decades later as RN numbers can be used for many many years
This is the formula:
Your RN # minus 13670 (first RN # in series)
Total #s between the original and yours/2635(average #s issued per year) = # of years since issue date
1959 + # of years since issue date = estimated year of issue
