Unsure of this Kozuka

[Ron M]

Hello all, thank you for thoughts on my previous post. 
 This kozuka seems a puzzle. The metal looks like maybe silver (been a rough road for it) and signed with either MitsuHiro something, or it’s a pseudonym for an artist name. I can find a MitsuHiro making silver kozuka but almost always with gold inlays only.

 I will make another post for the blade that came with this.

Thank you!

光広軒

 

Mitsuhiroken

 

軒 (ken) is a character you usually see at the end of art names, but I could find any such art name as Mitsuhiroken in Wakayama. There were several smiths who used the name Mitsuhiro, with the same kanji as the first two used on your kozuka. Of these, two of these smiths used art names which incorporated 軒

光広  whose real name was Kikuoka, and used the art name of 行風軒

光広  whose real name was Noda, who used the art name of 逍遥軒

Your smith might be one of these two, and the name inscribed on your kozuka was a name that was one that was in use before before a final art name was decided upon.
