This set includes a whopping twenty-four (24) sockets. Sixteen (16) hex sockets, ranging from 7/16” to 1-1/4”, and eight (8) square sockets, ranging from 3/8” to 15/16”. They have a unique interesting bell shape with all but the smallest sizes having a pronounced lip at the base. The walls are almost all knurled, except for a thin band of smooth steel finish, where each socket is marked with the “RAY” brand and its fractional size.
The sockets do no have model numbers. Neither do the long extension or the drive plug. The handles do, including a speeder (410), a short brace type speeder (510), and a Tee spinner (710).
The ratchet is not numbered and never had a model number as far as I can tell. If there was a handle with the model number 610, I’m not sure what it would be. Perhaps a hinge handle.
All the tools are nickel-plated.
The clasps on the handle-less attache style case are marked LANGENAU / CLEVELAND, a manufacturing outfit that is, ironically, still in operation today.
