I've located the 14 preserved (aka not Broken up, not Written off, not laying in an airfield decaying in the Elements) Douglas Aircraft Company DC8s. These include everything from one of the early test aircraft to a late model stretched 70 model. They are located around the world in Museums, as Ground Trainers, one is a billboard and two have been converted into personal homes.

Thanks to the usual sources of pictures, aka Airliners.net and Flickr, along with a few other sources of the real hard to find pictures of surviving aircraft.
Some surprises when I went down this rabbit hole.
