This is a vintage set of meters by SUNCO. I tested the engine vacuum and battery both work, stopped there. The ignition, battery, and generator-alternator are cosmetically in excellent condition. The engine vacuum is held together with duct tape. The Dwell- Tachometers shell is heavily degraded but somehow still holding itself together. 4 of the five have their paperwork as you can see from the pictures. Comes in a solid red carrying case from the school district of Waxahachie TX! The carrying case itself is in solid condition has the words Tune up test set written on the outside
