Ohio Ca*e f0 . , *tiov< e**ient JUST as the small case often holds the finest watch or the finest camera, the Simpson Testing Instruments illustrated here are one more example of "good things coming in small packages." They are the final answer to every need for compact but versatile testers — built for life-time service — moderately priced. Like the larger Simpson Testers, these smaller instruments reflect the beauty of design, the unerring accuracy, and the downright dollar value that could only have been built into them by Ray Simpson and a group of associates who have made a life study of instrument building. There is a Simpson Instrument covering every conceivable requirement — each built to that high standard which can only be described as Simpson. Ask for complete descriptions.
