I picked up this WW2-era tsuka at a local auction because it is the only one that I have ever seen with a 3-5-3 paulownia medallion. As a bonus, it came with a portepee in excellent condition. I was wondering (a) if anyone here has seen another 3-5-3 medallion like this and (b) if the colors on the portepee indicate issue to a major/colonel-level officer?
