Canadian Barrel Bore Inspection Mirror

In a very good condition a Canadian barrel bore inspection mirror. It a tool used for inspecting the rifle barrels after cleaning, it has a small mirror inside a gap at one end of the tube, and the other end is put down the breech or muzzle of the gun, providing there is enough light around, the viewer can see the condition of the inside of the barrel. This example is clearly marked with the Canadian Broad Arrow.  A very nice item for display!
