Table schema:
CREATE TABLE table_name_66 (late_1943 VARCHAR, _late_1941 VARCHAR)

Question: What is the 1978 Veteran membership with a late 1941 macedonia and a late 1943 less than 10,000?
SQL: SELECT SUM(1978 AS _veteran_membership) FROM table_name_66 WHERE NOT _late_1941 = "macedonia" AND late_1943 < 10 OFFSET 000
