Gemini.
You may joke about the shortage of power, and yes I have flown them. The Gipsy version was a lot more spritely and there was a Continental powered one as well.
But, find anything newer that can carry 4 people in relative comfort on 2x90hp??
Oh, did I forget the fact that it is fairly quiet and handles well.
Shell had one for years and Douglas Bader flew it all over the place, until they got a Beech Travelair. I saw him in Gibraltar with it.
