Stainless Steel Airline Control Valve

I do not believe these were new. They looked nothing like the add pic. Instead, severely coroded on the exterior having a patina and the nickle plating falling off and removed. The interior of two valves were packed with a thick black greasy material blocking the air passage entirely. All were extremely filthy containing a thick black residue. I cleaned them with pipe cleaners and scrubbed them well to use them. I did get them to function and had no choice but to do so as i needed to immediately install and use them. However, i will not believe them to be new. Rather well used for years and if that not the case, then the controll valves were not stored properly at any point. The valves were excessively filthy for the money.
