I am lucky enough to have W.O Bentley's biography and there's a whole chapter on the aero engines he designed in WWI, yet I've never heard of any airplane from their era using a "Bentley....".
...actually, come to think of it, I don't think it was produced under his name, so it may be under another name.
Anyone know what I'm talking about?
What airplanes used his engine(s)?
