Mums

[Eaglelord17]

Oh another thing to add, the exact reason for removing the mum is still much debated. I have put a link I find fairly well written and provides a good bit of knowledge towards as to why this was done as there has been no 100% conclusive answer. I have heard of Americans on their way to the US with unground rifles being ordered to take chisels and the like to the crest, so it wasn't just a Japanese thing (and it also means that captured rifles didn't 100% of the time have the crest left intact).
