Vintage Aaron Cain Tattoo Machine. This one is the “Hook” I accidentally had named another machine as a hook model. I revised it. It’s from 2007 and authentic, Aaron signed this one in an unusual place it’s tough to make out but one can see it. Machine runs flawlessly if you know what you’re looking at then you know what this is all about I think it reads a low low number 17! I’m original owner.. Aaron’s signature/date/model/is on the outer coil shelf/frame itself she’s a great machine in great shape!
