My wife's great uncle recently passed away he was an MP and was in Japan at the beginning of the occupation an old man walked up to him didn't say a word just handed him this sword bowed and walked away.Fast forward to 2022 I found this sword wrapped up in a table cloth in the loft of his yard shed the saya was packed with grease needless to say it is ruined but it kept the blade from serious rust .Can someone please help me identify this sword as to period and maybe maker it is unsigned.68468996621__0D2A8414-C828-4F91-8FFE-BF0E3E28FB61.HEIC
