cool model cannon made from a Bofers shell & 303 shells , not sure what to call this, its a model cannon but its also what you can class as trench art but its highly unlikely to have been made in a trench.

the muzzle of the model is slightly loose & has some tape around it to make it sit snugly inside the shell, it is marked but I think it's actually a piece of an old telescope? fits the purpose well.
a great piece whatever you wish to call it.
