Iron Dragon Tsuba Attribution?

[kyushukairu]

I acquired a new tachi which came mounted with this nice big iron tsuba, though I was wondering what school you think it would be attributed to.
My thoughts were 'Mito', though I'm more au fait with kinko schools than tanko, so I'm not too confident. All opinions appreciated

My kind of Dragon tsuba...well done.

If you look for JAKUSHI, you will find similar items.

3rd for Mito.

 

This is one I have (NBTHK Hozon), it's large like yours and the general detail work I think is similar:

Thanks for the suggestions, chaps. I don't think it is Jakushi, however. Whilst Jakushi achieved a similar effect through etching with acid, their etching doesn't have the same level of depth as this one. Also, Jakushi school applied nunome on top of the relief, which this tsuba lacks - though there is gold inlay for the dragon's eyes. 

Steven and Jeremiah, I think you are right, as I was initially drawn towards Mito. I can certainly see similarities with yours Jeremiah, though the iron looks wet. Perhaps mine just needs some choji and TLC.
