Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_54190 ( "! Late 1941" text, "Late 1942" real, "Sept. 1943" real, "Late 1943" real, "Late 1944" real, "1978 Veteran membership" real )
