@mdiddy Thanks for the response I did notice the difference in the nakago between the two. Everything else I own is shinto or older so beyond the forums I can not compare in hand. The other in military mounts I believe to be a koto blade so side by side they are pointless. I agree that the nakago is much cleaner than the typical Chinese examples that I have seen. I also wish it had been signed but was unable to remove the tsuka before purchasing. If the price wasn't so good I likely would have passed on it, but since I never see them at estate sells or yard sales I rolled the dice.
Is there anything else you would like to see on it specifically or any additional pictures? I guess the big question now would be does it just get locked in the safe or would it be worth a window out of curiosity? In the current state, it is very hard to pick any details out on the blade.
