I just bought this item from an auction where it was advertised as the top of a Japanese landmine. I don’t think that’s what it is. It has a marking of two crossed cannons so I think it’s an artillery fuze but I’m not certain.

Can anyone tell me what this is and what type of munition it belonged to? Any help on age and rarity would also be appreciated. Also, any information on what the markings mean would be helpful. I’m a little confused by the Mercedes looking mark.

Thanks!
