While researching port of arrival immigration forms from the SS Bremen out of Bremen Germany in 1927, some entries have the code S.COL.23 as the answer to the "By whom was passage paid?" question.
Any idea what this means?
Update: Doh, the comment by @J.J.D. that says "See Column 23" is correct, that column is "Whether going to join a relative or friend; and if so, what relative or friend, and his name and complete address". If you restate your comment in an answer, I'll accept it.
