Shinshinto utsushi maybe Jumyo school
Hamon: gunome midare with tobiyaki in ko-nie deki, sunagashi in monouchi
Hada: tight itame (hard to tell in current polish).
Quite long with a heavy feeling in hand despite the slender sugata.
It comes with a nice koshirae with all en-suite fittings depicting Kamakura era battles (Genpei wars), bottle green saya, silver foiled habaki.
Tsuba is signed "江刕彦根住" "Koshu Hikone ju" but most likely gimei, nonetheless a nice piece.
Some surface rust, but no other defect.
Price is 3600$ (slightly negotiable) plus Paypal and shipping
