Yes it does !! The Morimura brothers went through several marks !! I think what happened is the older mark was overstamped with the newer one !! It happens ocassionally !! I could find nothing relating to the word “trial” but perhaps that what they were referring to !! Trial of the new mark, , some how this one got stamped with both marks !!
It looks like it is WI-Hand Painted but this item appears old an is hard to see. Also, it appears that the center seal has a fish on the left side pointing down, a center symbol and another unidentifiable symbol opposite the fish. After looking at the mark under a larger magnifying glass, you can see that the ink may have dark originally due to small dark specs appearing throughout the stamp. Thanks for taking the time to help.
