Looks right to me. The Inshu Kanesaki smiths are a little difficult to track down it seems. There is a tendency for them to use the Kanetsugu mei early in their careers before using Kanesaki, it seems. Have a look at this one, http://www.nihonto.us/INSHU%20KANETSUGU%20KATANA.htm I think this one would be before yours but the later Kanesaki smiths seem to have produced hamon that show their Mino origins but in rather restrained style as far as activity within the hamon goes, whereas yours is much more interesting from that point of view.
As far as I have been able to discover the school begins with Mino Kanesaki in the very end of the Muromachi period. He seems to have moved around a little before settling in Inaba. The lineage then runs through to the Meiji period.
Not directly connected to yours but the same school see this one, http://yakiba.com/Kat_Kanesaki.htm
If you find out anything more about them I would be keen to hear it. I have been looking into them for some time.
All the best.
Promise I'll stop soon but here is another one of the lineage, http://www.to-ken.com/full.php?article=sr000090&type=swordRegister
