Hello
I would like to ask you for help in identifying the Mon or confirming the results of my research.
On the saya of daisho koshirae, the Mon is Maru Ni Mitsuboshi.
According to my findings, the Mon could belong to Katsura Kogoro, later Kido Takayoshi.

There are several people with this Mon on this link, but only one is a samurai.

Katsura Kogoro was later renamed to Kido Takayoshi (木戸 孝允) in 1869 and use another kamon (chrizantenium)

However, I did not find any other credible link that would confirm these findings.
I would be very grateful if you were interested in this character and would share your knowledge.
I attach some photos.
Of course, the family crest belonged to the Katsura family (or other family), koshirae may not belong directly to Katsura Kogoro, but to anyone in the Katsura family, ...but it is still very close to this important man.
thank you very much
Mayo
