Blohm & Voss BV 141
These images come from the June 1942 issue of Der Flieger, the june 1942 issue of Der Deutsche Sportflieger and the original pilots manual of the Blohm & Voss Bv 141.
Although this isn't a real close-up, these images are the most detailed available I know of, and therefore should be of interest for those 'into' the weirder side of aircraft design.
