which I've yet to see any spaceship have apart from mine.
This frontend is well known, and in fact the first known spaceship in D&N contains it:

I'm talking about the Double Engine which a few ships I've found like the Wicker ship have

Anybody know of a spaceship that would match this wick speed to create a new spaceship?

It looks like the wick burns at 6c/8, which is faster than the fastest possible orthogonal spaceship speed in Day & Night.

Sorry, I included two copies of the one ship to make comparing the front and back ends easier.
Here's a p6 thing that I'm hoping also is new. Stabilization could probably be improved.
