Here's one I made with a bit of cross kitting. Since there is no 1/144 kit of a B-50 that I know of I looked around at the options and decided that the fusealge of a Fujimi B-29 and wings and tail of a Minicraft Boeing 377 would do the job. I also had a set of decals for a B-50, in 1/72, which I shamelessly shrank to 1/144 on my trusty computer. Here is the result :


And here are three more that I made earlier:
A Huma Me263

An Amodel Antonov An-32

And an Airfix B-29
