Here is a very tired mostly cardboard and paper model I built also in 1973 of the LZ-4, the first Zeppelin, or any aircraft for that matter to stay aloft for 24 hours straight. After it landed, much to the dismay of Count Ferdinand Von Zeppelin, it was struck by lightning in a bad thunderstorm and was destroyed. Can't remember what German town this all took place in, or the exact year, but I think it may have happened in around 1908(?) As with my Viktoria Luise, this model is approximately 1/200th scale, and was made mostly out of department store gift box cardboard, but this one has paper nose and tail cones with no balsa wood stringer frames inside it. It is spray painted flat white. a little more accurate color than what I painted the Viktoria Luise in. To be 100 percent correct this model should also be a tan/ light yellow cotton canvas color, as I was told, these early actual Zeppelins outer panels were not doped at all, but left unpainted.
Just a note that the Viktoria Luise was a later airship than the LZ-4, which was still basically an experimental ship. It was about 400 feet long. The LZ-4, that is.
