Second drawer has several repeats of 1/2 and 3/8 sockets and are 6 and 12 point sockets. Also hansing trays only go up to 27mm and middle tray in drawer 2 goes up to 36mm. I believe several were extras I accumulated over the years, all 20-25 years old, as I beleive it was from 2 sets and the grey divider trays were purchased long before the Hansen trays so I figured to put them to use.
