This yant is rarely tattooed, but is possible to tattoo. The Master Hlwong Pi Pant has this tattoo in his pantheon, as i have seen it tattooed on army officials there at Wat Koh poon. Taw Waes Suwann, or, Lord Guberan, is the Lord of the Northern Quarter, and one of the Maharachiga Lords (Naharachiga is one of the higher realms of the Universe). Lord Waes is reputed to have given the Buddhs Sakyamuni a kata used in his conquering of Mara.
If you would like to read the story and background history of Lord Waes Suwann, you can visit the Thai Brahmin Portal and blog, where i have published a synopsis of the legend both from Thai Buddhist and Hindu brahmin viewpoints.
