1940s hotrod vintage AC Spark Plug chrome hand tachometer w/original box

Vintage 1940s or early 1950s vintage AC Type 1 Hand Tachometer. This hand tachometer still has the remains of the original AC Spark Plug (the predecessor of AC Delco?) box and paper instruction and service insert. The instructions appear to be dated 1948. There is only the hand tachometer (as shown in the photos) without the extension, couplings or special tip. The glass tachometer readout face is intact with no cracks or chips and the readout moves when we turn the shaft, we're not sure how accurate it is. There is light rust dotting to the chrome and wear and soil to the tape and instruction sheet.
