I have been studying the sig or mark but a clearer image I cannot supply. It is small and I believe that it's meant to be seen with the naked eye. It appears to have been made by the smallest engraving tool the artist had at the time. I was hoping that a direct interpretation could be made off of the art on the bell and the vague outline of the mark. I understand the difficulty when reading chinese traditional and japanese. If all lines are not very distinct then its a bear, but to a familiar eye maybe someone could say " It could mean this", or "it looks like such and such".
My gut feeling tells me "for what thats worth" is that this piece was hand made. Molded, poured then inscribed. I think that the battle depicted on it refers to an important battle and that its not just for decoration. Why else would someone take the time required to make such an impressive piece. That's my impression but hey, who knows. Also it has a very clear and long lasting ring when struck.
It seems I have a nack for finding unidentifiable items. I was the guy who found this metal detecting....
I have shown this to everyone I possibly can, even experts that teach in big universities. No luck with it either lol.
