Can you please help me with the translation

[Erwin 27]

Dear all,

 

Today I was able to buy a Shin Gunto and you were so very helpful in translating the Mei to Mishina Yoshiaki. While picking up the sword today, the seller showed me a Naval dagger which had a signing as well and wonder what you think of this. The blade is in a pretty poor condition unfortunately

 

Thank you for any assistance you can provide

 

Best regards and have a great day

球 (Kyu) seems to be the character that you are showing upside down.

Not a problem!  Actually I started to investigate what the character might mean, but then I thought it better to leave the fun part to you!
