If you go to Hershey, there is guy in Red Field to the right of the stadium that has nothing but USA made old stock tools. Most are new, and are reasonably priced. There are new and used tool sellers there too. Good thought about getting your old one calibrated and or repaired if the company is still at it, or someone does that type of work.
Don't forget to get the calibration of your precision tools - torque wrenches, meters, etc. - checked and corrected if necessary every couple of years. Most industries do it annually, but they have higher usage rates. FWIW
