The problem with the color GIF drawings is that in internal arrangement is not modeled

My earlier GIF drawings had two advantages. One, I followed Frank Fox's advice about always making an inboard profile, showing machinery and magazines, before doing an outboard profile. The other is that the resolution was greater, so details could be more accurate. The downside is that they were too large to show directly on a blog page. They have to be converted to JPG and reduced to fit.
