Japanese Branding Iron glory - honor B3-32

This is a vintage branding iron called a yakiin. These were/are used on wood, leather...food...anything you want to brand. Please see the last picture to see an example of how it can be used. I think they would look fabulous if used in pottery as a stamp. Also...I think they could be used with ink but as it is metal, the image wouldnt be as smooth and clear as a rubber stamp -please keep that in mind if that is how you want to use it. This is ei which means 1. glory, honor 2. flourish, prosper . They are from the 昭和 showa period . The showa period is from 1926-1989 but these are at least 30 years old. This is made of iron. Please look at the pictures carefully It measures 21.5cm long x 2cm (the stamp) wide.
