Previously owned Sata nozzle set in very good condition. 1.3 Jet 2000 is the model on the spray head, 1.3 on the nozzle itself and 1.3 on the needle. This item came in a tool lot bought at auction. I do not know the history on it. It appears to be have been used carefully and properly cleaned. I am NOT an auto body tech, so please ask any and all questions before bidding. Buyer pays shipping.
