This is a rusty old iron military fan (gunbai). Approximately 44 x 22 cm, weighs about 900g. I'm not sure if it was for military use or for a sumo referee, but it's heavy, so it seems difficult to handle. As you can see in the photos, there is rust, scratches, and dirt, but if you attach a strap, you can use it normally? You'll have to judge the condition from the many photos, but the September Grand Sumo Tournament is also approaching, so please consider it as a cheering item for your favorite wrestler.
