One of the types that has caught my eye was the Vickers Type 61 Vulcan, which was a proposed single engine passenger transport that Vickers built around 1921. It had a checkered career as an airliner. I like it because I have a soft spot in my heart for tubby ladies like the Vulcan.
The other type that caught my eye is the Boulton Paul P 64, which was a proposed mail plane. The prototype proved to be somewhat less than acceptable, and so Boulton Paul tried to improve the design with the P 71, but, sadly, that too proved to be unacceptable.
I wouldn't mind attempting to build a model of this, if only because of the nonagonal cowls of the engine nacelles. Besides, like the Vulcan, this design holds a lot of character, at least to me.
