Legodrome‘s 190-stud long Bistouri spaceship comes from the Metabaron comics. Did I mention that it’s 5 feet long? The size of the ship is deceptive due to the large triangular fins that could be easily replicated on a smaller scale. The brick-built skull design from a close-up view should convince you of the true size of the model.
Reminds me of the Kestrel from Escape Velocity.
Maybe worth noting that Bistouri means “scalpel” in French.
