Thanks for the comments.

Interesting Steve. I think that's a characteristic of most muti-engined types with inline engines as opposed to radials. It looks more marked due to the narrow profile of the cowlings. The Renault 12S 02-201 power plant is an inverted Vee 12-cylinder engine (a similar arrangement to the Rolls-Royce Merlin). It might look odd if you're used to radial powered types. I can think of several twins with a similar configuration, like the DH Mosquito & DH Dove. I don't recall any reported vibration problems.
