Nihonto Club

We have a family mon on the fuchi. Has a lot of gold highlights on it. We are wanting to find out if where it is located does indicate the rank of the officer or the rank in the family where the mon is. Do you know how to research who the officer was through the mon. It is off a WWII piece, shin-gunto fittings but higher grade fittings. There is a name scratched into it.
