I’m not sure if that link’ll work (sorry never tried that before). Dunno which pic you mean but i wondered if this’d be any good to start off from?

The address i found it on was http://3.bp.blogspot.com/_ax5ZIdFoW1U/Sq748qbMcSI/AAAAAAAAVOg/T5LMZ6ks2l0/s400/gun-tattoos-32.jpg Good luck – hope you find what your after. Its really annoying when you have it in your head but can’t show anyone!! 🙂
