I apologise for not meeting your expectations and wasting your time Marius.
While this wasn't meant to be a joke, it was meant to be only a casual fun kantei, as no one else could hold the blade in hand, and I do not have the skill or access to a scanner or good camera.
After seeing some recent kantei threads I thought it would be fun to share something similar, but perhaps it was foolish to do so? Nevertheless, consider me properly 'photo-shamed'. I will certainly curb my enthusiasm and refrain from posting similar content in future for fear for upsetting some of our august members here.
Thanks to everyone for having a go. The answer is Kashu Sanekage.
Ko-uda would have been the closest guess, as also Hokurido. Hojoji was an intelligent choice. It has many similarities as Tajima was just geographically down the coast from Kaga and this is a naginata naoshi.
The ooitame hada and whirlpool hadatachi with chikei and jinie has Norishige influence (and Hokurido) but not quite matsukawa. The nie laden hamon with hataraki is Soshu but the gunome ko-midare again is different and doesn't have the indistinct border of Norishige.
Anyways it is a heavy beefy blade and great to hold and look at. Tanobe sensei seemed to also have a positive impression of it on his sayagaki.
