As far as sword canes are concerned, they are an illegal IMPORT to New Zealand but there are many in collectors hands here. I have never owned one myself but have owned a .410 cane gun (British made). Pic below (sorry for quality) with other stuff I had at the time. Also a link to Poachers Guns which you may find of interest
