KO Lee used to make tool and cutter grinders , so possibly has something to do with it . Hard to tell by the pics .

It appears to be se set of collets, Needs a T & C grinder.

They still do.

They made a lot of other stuff too, like expanding mandrels and automotive speciality tools, yes, that collet set and master were likely used with a T&C grinder, but long ago; I just disposed of a bunch of KO catalogs on e bay, and saw nothing like what is shown in the picture, the box looks like 40s or 50s.
