Tyler Hepworth found the answer:
The mystery instrument is a circa 1919 combination
voltmeter/ammeter used for troubleshooting electrical systems, ignition testing, and cadmium testing on batteries. It was
marketed primarily toward repairmen in the automobile industry. The item was marketed along with a set of 14 instruction books
encompassing 3000 pages that contained detailed instruction on locating and troubleshooting electrical problems, over 700
wiring diagrams, a 300 page book that covered every aspect of automobile batteries, and a set of cadmium test leads. The entire
package was billed as the "AMBU Trouble Shooter". It sold for around $200 which is equivalent to about $1800 dollars today.
Sources Sales documents at the end of the book "The Automobile Storage Battery: Its care and repair".
The book was
digitized and made available by Google and includes the advertisement for this gadget.
