Hunting and collecting vintage garage gear can be nearly as fun as driving cars of the same era, and nothing complements a fine old driving machine like a few well-chosen vintage accessories—particularly a classic diagnostics machine.
Engine analyzers, distributor testers, oscilloscopes, and other diagnostic equipment of the time were fine pieces of engineering and craftsmanship in their own right, built on heavy, all-steel chassis and with glass-fronted gauges, etched lettering, and great graphics and colors galore. If you’ve got a few spare square feet and don’t have any philosophical qualms with harboring a tool that will most likely never earn its keep, there’s no cooler way of highlighting your parked classic.

I recently needed a new tach/dwell unit and found I could get a used vintage Snapon for the same price as new cheapo plastic one. After cleaning off layers of nicotine tar I tested its accuracy against another unit and it works perfectly. As you say its well made and looks cool in my garage.
