Here is Schrader Passenger Tire Gauge. The Gauge is marked:
REG. U.S. Pat. OFF
Passenger Tire Gauge
A SCHRADER'S SON
Division of Scoville MFG. Co. INC
Brooklyn, N.Y. U.S.A.
The gauge appears to be stainless steel. It is in very good condition, it looks like it got very little use. There no dents, dings, nicks or rust. The gauge numbers are clear and sharp. I tested this on our car twice and It worked perfectly.
Please ask any questions you might have. I will be glad to answer them.
Thank you for looking.
