This is a very rare item, I cannot find one like it anywhere. What is clear is that it is made of silver (tested) and that it is an most impressive lantaka cannon. Most have been on the desk of some official around 1920 ies, I would guess. May be older than that.Very nice condition (silver is not very strong material) and most parts are hollow or it would weigh more than the nearly 400 gram.

Of course this cannot was never meant to be fired, just a fantastic decoration piece!
