Shimabara Rebellion Guns Antique Japanese Military Ship Postcard

bg962 Antique Japanese postcard circa 110 years ago origin or older, that reads on the front "An Iron Ball For Guns Cast In The Shimabara Rebellion And Stand At Ohato" - some aging but fairly mild, light surface, and very small top left corner indent (just to very edge) - overall this is mostly great condition and has such character for any Japanese military collector published in Japan so I cannot traslate the writing on reverse (unused).
