Dad gave me many sets of tools over the years. He was a WW2 vet and a self-employed plumber from the forties to the nineties. One of the sets he gave me was a v series saltus set. It was mostly complete and I just need one more to complete the set. My first question is whether the socket end is supposed to be somewhat tight or loose and floppy? The second question regards the pivot pin. Craftsman used roll pins while most others used solid pins. I have seen some comments praising roll pins. Which are stronger? Best regards.
