This is a rather hard to find and very high quality original biddle hand held tachometer. It was made in switzerland and measures rotating speed from 30 to 50,000 revolutions per minute. It is in excellent slightly used condition and is in it’s original case with all of the attachments still in their places. The original instruction card is still under the loop in the cover of the case. The case measures about 7 inches long. These tachometers are extremely expensive new and are top of the line instruments. They are great to have at your disposal when determining the speed of gas or steam engines or dynamos or other equipment that are being driven by them. The pictures tell the story on this nice one. It’s as close to new as you could hope to find.
