I created a new thread about this interesting sword and its features in the nihonto discussion as it deserves, the other thread was just about the auction. I looked up Munenaga on google and in googles photos of Sesko's book it shows there were 8 or more smiths apparently named Munenaga. I knew the koshirae was obviousIy not this swords first as it was made in the late Edo period and the sword is supposedly early Edo but this koshirae is not a recent put together but koshirae that was made for this sword and mounted on it in the late Edo period according to the seller at least. I know koshirae is not perfect, the sageo is missing, saya was restored and repainted and there are nicer looking sayas but the tsuba, fuchi, kashira and habaki look to be of a decent quality. The tsuba looks quite expensive and complex, I have seen similar tsubas alone sell for $300-600 on ebay. The habaki is original edo and I see a lot of nihontos with repro modern made replacement habaki for some reason. I doubt this nihonto is shinshinto as the nakago looks too old.
