nihonto with limited information

[Malvolio]

Hello!

 

I wonder if anyone can help to identify or verify some facts about this sword. It has no papers. The owner believes it to be made at the end of the Bunsei period, so around 1829 or 1830. I read the mei as "藤原兼先" so Fujiwara Kanesaki, but that doesn't tell me which Fujiwara Kanesaki.

 

Unfortunately I can't currently get any better pictures. I may be able to after some upcoming travel.

 

What do you think of this, based on what little I've got?

 

Thank you!

The first 2 characters are 妙一 or "Myoitsu"

 

There was an Inshu smith Kanesaki that would also sign with Myoitsu but a quick search only turned up results that included more full mei (Inshu ju Fujiwara Kaneaski) 
Inshu Kanesaki (Some of the kanji look a bit different but this isn't my specialty)

from Markus Sesko's book:

Thank you both!

 

That's useful and appreciated.
