This socket set is a homeowner grade set. It is made in Taiwan in the early 1980s. These were actually part of a "sample" run that was not bought into. These are 12 point. They work on both metric and standard. These are not the MODERN taiwanese sockets. Those are 6 point (or lobe). 

This is not a heavy duty mechanics set. Good for simple furniture assembly and so forth in the house. Below are the sizes, they come in a red steel box.
