File talk:Rotary Piston Engine 8b03590r.jpg

The title of this picture is inaccurate. This is a picture of a Radial reciprocating piston engine, not a Rotary Radial engine. Rotary Radial engines had long since stopped being built by the time WWII came along. 70.113.89.227 (talk) 02:12, 13 March 2008 (UTC)
