OK! Yet another sword from someone over on AR15.com...
This was the info he gave me, not sure how accurate it is...
"Based on the MEI I believe this is an "Emura Chounsai" blade. It is said he ran a prison in Japan before and during WWII. They say he made blades himself but that his students/prisoners also made blades in his name. I am trying to confirm that it is an Emura blade, and if so, can it be determined if he actually made it. Either way my end goal is to see if it is worthy of a polish given the cost of such service.
At this time there is no Hamon visible to my eye"
Doesn't look too bad to me...but I am no expert!
