I have my Craftsman 150 ft/lb beam torque wrench I bought probably 50 years ago, and the white, black and blue box it came in. I also have a used Plumb I bought, which I suspect is older.
I don't think I've had mine quite that long. Mid 90s I think. Still quite accurate and in good shape, but can't say I have a lot of occasion that I use it any more though.
I use my 40+ year-old beam type, with female-to-female couplers, for DIY calibration checks of my click type wrenches. It's been a long time since I've used the beam-type for anything else.
