CREATE TABLE table_204_77 (id DECIMAL, "number" TEXT, "builder" TEXT, "type" TEXT, "date" TEXT, "works number" DECIMAL, "notes" TEXT)

what builder comes before ss & iw ?
SELECT "builder" FROM table_204_77 WHERE id = (SELECT id FROM table_204_77 WHERE "builder" = 'ss&iw') - 1
SELECT "builder" FROM "table_204_77" WHERE "id" = (SELECT "id" FROM "table_204_77" WHERE "builder" = 'ss&iw') - 1
