Hello again,    Welcome to another thread of me buying/rescuing an out of polish mumei sword that I found at a local gun sale.    I was attracted to the hira zukuri, and also the hamon. Unfortunately the condition, chipping, and rust have obscured some detail. I struggled to get good photos of this one, so apologies for that.   Any opinions welcome! I’m particularly interested in opinions on its age. It’s in a ww2 leather covered saya, and some civilian fittings
