Extensible Wickstretcher-like Spaceship

description Hartmut Holzwart has found a Lightweight Spaceship convoy which consists of a Period 4 wickstretcher head, a Period 19 wick and a Period 4 fuse. Shown is the simplest version with only one copy of the wick and one with two copies of it. (Note that there are no known Period 19 oscillators, so finding stable ends for this wick may take a while, but it could be the foundation for such an oscillator.)
