Hi Eric, it was noted that the sword was matching, presumably by the serial number? Is this indeed the case?
A disclaimer is in order. Japanese officers did use and modify Type 95s. They could either rent or purchase them outright. It is a rather hotly debated issue when these hybrids, a Type 95 blade with officer fittings or vice versa, appear.

The leather sword knot is causing verdigris to form on the crossguard and should be removed. Also, some greases can stain the blade, so it would be wise to remove all the grease from the blade. Replace it with a substance that is more blade friendly.
A finally, some better reading material for your edification.
