Nauticalia

This is a vacuum engine, or to be more technically accurate, an atmospheric engine. Intriguingly, on each stroke it "swallows" a gulp of fire. Steam plumes from the aluminium "chimney", giving the whole thing the appearance of a smoking gun.

Base measures 8x5", height 6", weighs 4-lb.

KIT FORM, all parts fully machined, ready for final assembly, taking approximately 2hrs.
