Flagstaff resident Bill Buehler holds up a rusted part from a 1942 Stuart tank from World War II, which he is restoring. In his left hand is a cardboard pattern he made so he can fabricate the piece for the restoration. In the foreground is a turret that will be set back on the tank soon. Buehler said he has been restoring military vehicles for 25 years and eventually sells them, usually to museums
