Leave it as it is. As per the mei on all big name swords, whether good or bad, " The blade will tell you(before) if it's good or bad. Your blade is not near top quality. In fact, the mei is impressive, but gimei. The habaki is quite nice. It still is a complete attractive package.
Tony, to get the true curvature, which is most important,if you hold the blade up right,holding the nakago so the mune of the nakago is vertical, this would determine the period.
It appears to be saki-zori, muromachi period. The long nakago, also suggest that period. It is a nice sword, whatever the period it maybe.
I am sure that is absolutely correct, but this is a well known upper tier mon illustrated in mon books. It was sealed on the tsuka and had a famous kaji.
I haven't a picture to show you, as I have a 2007 retired HP and don't know how to transfer a picture. Has two bananas?that over lap each other. They could be carrots or eggplants? The style is similar to Asano Family mon. Pinterest site, list (illustrate) Kamon -Crest Japanese it is # 69 on the list.
I remember seeing another excellent tachi mei Naotane dated, over 40 years ago with same bold strokes and identical yasuri-mei. Besides being dated it had an inscription referring to 5000 years ?..................... all I can recall. Should make it easier to locate in Juyo listings etc. Length was around 28 inches plus.
You have a very fine sword, excellent. I am leaning towards shoshin, if it's not Naotane it's the best gimei I've ever seen. Congratulations.
One Tom to another Tom I love it!
Quite impressive, actually remarkable, you're one serious dude. You had Leno drooling all over your Magnolia Special. Totally a great set up for your outstanding collection. Thank you.
It works the same way, when dealing with oversea auction houses, like Sotheby's and Christies,they forward it to their broker (NY) service in US who ships it to the buyer, charging ($100.00 to $500.00) for their service fees. They don't allow pickups.
