USA Made in Chicago, Ill that Fender got their parts from in the 1950's, 60's etc. I have 1 Photo of a output jack ( the only photo here with the lead cloth wires soldered on) from a 1959 Fender Strat showing the same stamping
These jacks can be problematic and they do wear out. Get the Full Bell Tone from your Fender Strat, or any Fender Guitar with Full Output!
You get the output jack with the washer and nut. Nickle plated and built Tough!
