Excellent. If I extend the bore down to the touch hole does it need a licence?
I think it would, though as usual nothing is ever easy. The Home Office Guidance (my bold) says:
2.3 ‘Firearm’ means a lethal barrelled weapon of any description from which any shot, bullet or other missile can be discharged. This includes any prohibited weapon, whether it is such a lethal weapon or not, any component part (see Chapter 13) of such a lethal or prohibited weapon, and any accessory to any such weapon designed or adapted to diminish the noise or flash caused by firing the weapon.
2.4 ‘Lethality’ is not defined in legislation, but the Firearms Consultative Committee in its Eleventh Annual Report and the Law Commission in its report of 16 December 2015 recommended that any barrelled weapon with a muzzle energy of 1 joule or more should be considered lethally barrelled. However, this is a complex issue and, although case law exists (Moore v Gooderham (1960), only a court can decide whether a particular weapon is capable of causing a lethal injury and would therefore be considered a firearm for the purposes of the Acts. Providers of forensic science services will be able to advise in any case where ‘lethality’ is likely to be an issue.
The Crown vs Model artillery might make for an interesting court case. Although a model cannon could be 'lethal' within the meaning of the act and well in excess of 1 Joule, it's obviously not designed for that purpose nor is it a practical weapon. It wouldn't be easy to injure someone deliberately with one, though I suppose a nasty accident is always possible.
I'm afraid criminals, terrorists, fools and too many deranged legitimate gun owners have spoilt things for everybody. Mind you, I doubt the police would be interested in a model cannon decoratively posed on a mantelpiece. Firing the same in a town centre would probably get you introduced to an armed response unit, a psychiatrist, unsympathetic judge and a prison cell.
