Cool video.  I know it is an antique, but would have loved to see it fire.   Interesting concept as well.   It has been a long time since I have looked at the plans, but that moving mechanism seems similar to the feeding mechanism of a proposed combustion engine that used blackpowder as fuel.  The needed one of these on the Sharpe's movies to go with Harper's Volley Rifle.
