Tsuba With Name But Not Go

[Ludolf Richter]

Hi experts,

one of my Tsuba has only a 3-digit-name but not the Go from the artist.Am I right with "Harutensha"?

Does anybody of You know this artist?I believe the reliefs are done by acid etching.Ludolf

Is this what you see? 晴天舎 Seitensha or Harutensha. Neither appear in the index. John
