Another Inro, Netsuke an' Ojime

The real problem with this one is that I have none of the significant information about it. I have had such, by the same Japanese dealer, when he evaluated the other one. But I cannot put my fingers on it...it's on paper, not stored inna cloud or otherwise digitally. I'll keep looking, but hold small hope given the local chaos.
I am sorry for the pics...it's overcast & rainy, so available (LED) light...an' on curved, golden surfaces, or darkened parts of the accessories. Double pics of the single mark, again the best I could manage.
The 4-case Inro is ~ 3 3/4" high, ~1 7/8" wide; total weight is 57 grams. The Ojimi looks to be an eggplant, the Netsuke suffers from not being traditionally 2-hole pierced for the cord; it's tied around the stem of the larger mushroom, though fully captive there. The insect is carved of the same material, not applied.
If any of you can read the signature, I'll be very grateful.
Thanks for lookin'!
