Okimono of the Meiji period. Artist's name?

Hello

I have this beautiful Netsuke-like Okimono. I've gotten as far as I could to know everything about this piece; that's how I discovered this site.

This piece is about 6" tall and almost 3 lbs heavy. Beautiful detail!!

I'm not sure if this is Ivory. I think it is what I've learned it is called Polychrome Ivory, but again, I'm not sure that's what it is.

It has a "Red Lacquer Reserve" seal with a signature of the artist at the bottom. Any extra information is greatly appreciated!!!

I hope to be of assistance to somebody here soon!!!

Thanks!
