Shamrock has a picture of one here
here is an example of a non-SCA legal interpretation

I first saw it on Christian Fletcher's site, back when he was doing armour.
Where does the inspiration for the embossing come from? Does anyone have a primary source image, or is it just a SCAdianism that looks cool and caught on?
