    Not at the moment because it is dark. It must be engraved on the metal. I am going to take a closer look now maybe if I clean the dust off of it. Give me one second. I'll be right back.

    It reads: Bendix Tractor Protection valve 120 934 899 0670 manufactured 07/14. Five years old. It would probably need replacement in 2020.
