The Martin 167 bomber

The Martin 167 bomber had been built to compete for a USAAC requirement for a light bomber. The prototype was the XA-22. The Air Force Museum at Wright-Patterson AFB has a good page about the plane. From information at the Glenn L. Martin Air Museum, we know the production figures for the Martin 167:
