Need help with Tsuba Mei

[Itomagoi]

Hi, 

I pick up this Tsuba and need help with the signature. Perhaps Masaharu?

Bushū-jū Masaharu (武州住正春)

[Itomagoi]

Thank you, Manuel.

? My eyes can only see San-Shu, i.e. Yamashiro. 山州住正春

Am I missing something?

Hi Piers,

That's what it looks like to me, but I've googled Sanshu Masaharu with nil returns but there's lots for Bushu Masaharu so it might be our eyes that are the problem.
