Non-monotonic spaceship 1 is a c/4 orthogonal spaceship that was found by Hartmut Holzwart in August 1992. It was the first orthogonal non-monotonic spaceship to be discovered.
Other c/4 non-monotonic spaceship
In Keith Amling's Period-4 xWSS agar ship, another such spaceship is used for stabilisation, that acts more like a p4 pipsquirter, albeit still receding a single cell (as is the maximum amount a c/4 orthogonal spaceship can recede), but receding to a single-cell front row instead of three adjacent (so its frontend displaces by (-1,0,1,1) across the period instead of (-1,1,0,1)).
