The Potez 540 was a French bomber of the 1930's. Its first flight was in November 1933.
It saw service in the Spanish Civil, where it was used by the Republican side.
At the beginning of WWII it was obsolete, though the Potez 542 version continued to serve in the French Colonies and saw action in the short conflict between Thailand and Vichy France (December 1940-January 1941) over territories in Indochina.
