Help with Identification of Katana in Gunto koshirae

[Lexvdjagt]

Hello, I recently acquired this katana from a dealer in Japan. I would like to know your opinions on the blade and its history. The blade has some obvious foraging imperfections, and small spots of rust, some black rust and some red/brown rust. I have oiled the blade appropriately to conserve it with choji oil. The fittings are all serial numbered with the serial number 083. I would like to know if this is indeed a Koto period blade and if anyone has any information about the signature. As I have not found a similar mei anywhere.

Information from the seller:

Mei: 武蔵住守宗 (Musashi ju MORIMUNE)

Date: Koto period

Nagasa: 70,9 CM unusually long for a Katana, (closer to a Tachi?)

Nakago: 22,5 CM seems to be cut off maybe shortened?

Moto-haba: 31 mm

Saki-haba: 22 mm

Moto-gasane: 7 mm

Saki-gasane: 5 mm

Sori curve: 8 mm

Full blade length with koshirae: 105,4 CM.

Any information about this sword is much appreciated. I am still beginning my collection, so any basic advice would be more than welcomed as well.

 

If any additional pictures are needed please feel free to message me.

Lex,

there are two more KANJI in the signature which are difficult to read for me. 

The SUGATA of the blade with its little SORI reminds me of KANBUN era (early EDO JIDAI). The blade is not at all too long for a KATANA, and the signature is KATANA MEI. The blade does not seem to have been shortened a lot.

Just my 2 YEN.

To me it looks like:

 

武蔵住尾張守宗... = Musashi-jū Owari no Kami Mune... [the rest of the mei is missing]

 

I have not been able to find any reference to a smith who signed this way though.

without looking into books:

shape does suggest Kambun shinto.

Signature titles are typical for Edo period

It seems to have certain Yamato hue to it, so Owari connection (even though the title does not really attest to it) is possible, as very many Edo smith came from other provinces and suguha is not too common there.

It can be an unlisted smith.
