Okay guys I went a took the bolt out and the blade came out easy. Here are some pics. It's probably near 4 feet long and I only could find 1 marking on it. https://imgur.com/a/z9dAjQi

Greetings everyone Images: http://imgur.com/a/nvgtp9a This sword is claimed to have come home after ww2 via my father's uncle. No I dont have pics of the tang / markings. Dont know if its wise to undo that nut? And yes the tip is broken off because as a kid I threw it at a wood pile. But none the less can anyone give any information about it?
