I looked for a chart like that. Thanks. It doesn't seem to be any of these. I thought it was Torx, but none of my Torx fitted. I should have counted the points. They were more than the Torx, and finer. I had 8 sizes of Torx and none fitted. I just thought of what it might have been. A spline wrench might have worked. I remember them from working on electronic organs, but the organ ones were smaller.
