Kunitsugu, but which one?

[Dependazelle]

Hi, all:

 

I’m working on translating these papers. They are an older variety, so I’m struggling with them a bit. I know this is Kunitsugu, but I’m struggling to determine which one. It looks like maybe 4th Gen based on other Mei examples I’ve seen. I’m still very new to this, so I could be wrong. Any help would be much appreciated. Pictures below for reference.

As far as the papers they only go as far as to say that this is Echizen Kunitsugu. And I believe this is an NBTHK kicho ninteisho, rather than an NTHK kanteisho
