A friend of my son's is trying to identify this bike. Mister G and I think it may be a Villiers or DKW engine, with possibly a hand-built frame. Any other opinions?
Update: Many thanks to Jeff F. for identifying this for me. A Coventry Eagle it is! Specifically, a Coventry-Eagle Silent Pullman Two Seater, manufactured in 1936 and 1937.
