A Lowe, Willard and Fowler DH-4B postal conversion with two 200 h.p. Hall-Scott L-6 engines. Others had 150 h.p. Hispano-Suizas.
An American de Havilland converted from a single to a multi-engined machine. The engines are two six-cylindered Libertys, one of which is capable of maintaining the machine in flight. It is being used, in conjunction with the Martin "bombers" for mail-carrying, and is said to be nice and easy on the controls. -

I give another detail picture of this modification, which in earnest resulted in a completely different aircraft. In the nose was the large mail compartment. The pilot was in the back, seeing presumably very little forward. But the air mail post was delivered by these machines and lots of other DH-4's by the United States Postal department.
