Help With Mark On Japanese Brush Washer

[kardinalisimo]

Not sure how old if old at all but maybe if someone help with the mark I can figure at least the type of ware.
Thanks

I think it is done in Ogata Kenzan style.
Peter, any help with the characters?

Hi Kardinalismo, Im not sure, it looks like a studio mark and is Japanese, sorry I can't be of more help.

I tried finding a kiln/manufacturer with what I thought it might be, but found nothing.

Thanks for your efforts.
