"Anorak ON".
That is a mod by a Dr Bird by adding two Lycoming GSO-480 piston engines. Known as a 'Bird Innovator'. Only one ever modified and later returned to stock standard. I think the wing and tail were modified too. Gave more range and speed but overall not a successful venture.

That picture might be Oakland in California. There is a Short Solent that belonged to Howard Hughes still there in the local Museum.
