Ah, thanks for the additional detail. Unfortunately, we don’t have the crosswalks you are looking for and there probably is not an easy way around this issue. One possible solution is detailed in [this previous user forum question](https://forum.ipums.org/t/crosswalk-between-ind1950-and-sic-and-or-naics/419/1). Sorry for any inconvenience.
