We did not get out as far as Hiroshima,instead spent some extra time poking around the back streets of Kyoto and Osaka.
Between Gion and and our Ryokan, tucked away was what at first looked like a tiny junk shop. On closer inspection it was the most interesting 'Dump' of a shop that had everything from awfull sword mounts to two Tanegashima. The first was just a barrel, huge bore,12" in length and weighed around 80/100lb. The work was plain as are most hand cannon and quite deep rust pitting. The second was a better but wormed stocked Ten Mon,the barrela had remains of inlay and although signed was to rusted to read the characters.
So my luck was in!,to return home and off load the goodies would have rounded the trip off well.
The price when asked ........
