NTHK Paper Help

[DTM72]

I have just about everything figured out. Maybe I just gave up on the easy stuff. Help with the red circle please? Feel free to double check what I have.

 

Question about the attribution, I have found 3 Hichibejo Sukesada. SUK814 worked during Tenmon 1532-1555. This is probably too early for this katana, and there is no mention of "Takaki" on the kantaisho, so I can probably rule this one out.

Next is SUK879. He worked during Kanei 1621-1644 as well as SUK887. I would like to say mine is SUK887, but we can argue that later.

With both possible smiths working during Kanei, there no other Sukesada's (much less Hichibejo Sukesada) until Kanbun 1661-1673, the NTHK gave a timeframe of Manreki 1655-1658. Is there a hidden Hichibejo Sukesada working during Manreki that I am not finding?

 

Many thanks in advance to all.

Looks like you have done a good job, Dan!
I think the characters in red are just 有之 (*this has* a nagasa of 2 shaku 3 sun 4 bu).

Just a small note, the smiths name should be read as *Shichibei*  [no]  Jō  Sukesada”  (七兵衛尉祐定).
Regarding which smith the paper is referring to, I checked my books and couldn’t find a Shichibei  Sukesada  working in Meireki (1655-1658).
As you stated, the 5th gen was active during Kan´ei  (1624-1644), though he died in Enpō  2  (1674) at aged 98, so he would have been 77-78 if he made this sword. Although the 6th gen is given as being active in Kanbun  (1661-1673), he is noted as having worked as early as Manji (1658-1661). My opinion is that there is no hidden generation, but that the shinsa team were simply unsure as to whether it was the 5th or 6th gen.

Many thanks to you Dr. Shuttleworth! I am leaning more towards Godai. The few things I read about Rokudai is that his hamon had sugu-yakidashi. My particular example does not have yakidashi. That may be a moot point since the nakago is suriage.

I would happily pull you a pint of Guinness if I could.
