There are 2 versions one has + 10 focus the other + 5 focus....The +10 focus version there is only one of I believe, and I know there are at least several of the +5 version. Other than that I don't remember exact mods or numbers. I believe its called Obi Di Onse or something along those lines as well. There's one of each versions at Manticore's museum if I'm not mistaken.
