And the collection grows. On the double groove combo end wrench, am still shy the 3/8 and 13/16, have the rest up to one inch! Thanks everyone. The combo open end, combo box end, and combo box end offset are near completion. Now I have found there is a combo box end short! Going to start checking this collection in pounds! Just came across more of the earlier single rib combo and box open combo, so they are still surfacing. Have a white wall in the new garage, these may get arrayed there sometime.
