The CS was a completely new design and the first of the modern socket meters. When meter mounting arrangements were standardized in 1934, the CS's enclosure design was emulated by the other manufacturers. The CA was introduced the same year when a new standard enclosure was developed for the bottom-connected singlephase meters. The first CS and CA meters had the same alphanumeric serial number system as the previous OC meters (and use the same stator design). The magnet assembly on this group of meters were painted black as was done on the OB and OC meters. In 1937, these meters had two changes: The magnet assembly was now painted silver and the alphanumeric serial number format was abandoned, the first new serial number being #15,000,000. Starting in 1940 (#16,500,000) the magnet assembly got a heavy layer of copper plating for surge protection (but this method was not as effective as using Alnico magnets). During WWII, a limited number of meters were made and these have thin plated COPPER disks. Some CS and CA meters are known with cyclometer or odometer registers and these are not as common as the pointer-type register. This CS model is untested, but great physical condition! I'm sorry, I have no way of testing this item. This item is large and heavy.
