As a beginner I took this challenge with hesitation, but I guess one has to start sometimes doing kantei in order to make progress.
So, sugata looks to me late Kamakura or early Nambokucho. As the sword is shortened (as far as I can see) it should have been koshi zori and around 80-90 cm which fit the characteristic of this period, also somewhat chu kissaki is fit as well.
As for school, ichimai boshi (as looks to me) indicates Soshu den as other wrote, but Nagayama in his book says that this kind of boshi usually appears in late Muromachi, but nonetheless I stick to late Kamakura.
The hamon which looks to me based on o-notare also indicates Soshu den.
As for smith I admitt that I took a long shot, and basically it is more of guess to Go Yoshihiro.
I hope that I found out at list some of the characteristics , Mike
