Extremely well used Rental valve,has lvl 10. Powertube tip is removable. Tested the lvl 10 and it the bolt stops but has a lot of force so I would say the lvl 10 needs tuning. Serial is FG39071. Has dried gunk all over it. Valve is in extremely used shape but dry fired fine with no leaks when tested. Looking at the seals it likely will need a seal replacement/rebuild if you plan on using it. Has a red spring but has worn off red color. Has Field Rental engraved. Likely needs all seals replaced. No foamie in lvl 10.
