Toy or desktop cannon - non firing.  This means that no one has modified the cannon to be able to be fired.  Yes, apparently there are people out there who do that as a fellow eBayer informed me that my listing was strange that I stated it was non-firing.  They stated that they’ve modified this model to fire.  I’m strange?  Really?  Let me state that any explosions or injury caused by modifying this model for anything other than it’s intended purpose as a model or toy is the sole responsibility of the buyer.
