Just rescued this from a second hand store. Arbor 159 Abacus with the "Structurn" base, it has 2006 Cartel bindings so I am guessing it's from around that year. Looks like it was used once or twice as there is no wear on it except for a few very small nose chips. I am stoked I picked it up for just 65 bucks. So if someone can help me nail the year or a spec sheet that would be stellar.
