I bought this scope in 2007. It has been set up for the Argo Navis and the combination is fabulous. I have used it many, many times and it has been a great instrument. The condition is excellent and there are a few mods - rack holders on the side and the Argo Navis fixtures on the base and Altitude wheel. I reviewed the 16" in 2007 here -
