This kit was sold only through the Waltham Horological School. The gauge is 2 inches in diameter and has many different holes that correspond with the bottles in the kit. This made it very easy to locate replacement end stones for pocket watches. Two types of end stones were used. Sapphire and Ruby.
Many times watchmakers would also use this kit to store other jewels such as balance jewels as the gauge made it very easy to measure them.
The metal gauge was made by E. H. Swain and was copyrighted in 1908. The gauge holes are in 1/100th of a millimeter.
A very useful and functional jewel kit. Very hard to come by the whole complete kit, but the gauges are kind of common.
This picture shows the instructions for using this kit.
