Here’s a classic 3/8” b and d from I believe 1960 ish time period . They just don’t make tools with this kind of quality anymore. I don’t believe it’s had that much use  in the 60 some odd years it’s been around not perfect by know means but the chuck is in very nice shape . In the pics you should see the battle scars . The chuck key is not the original I don’t believe.  The grinding stone is cracked and the box has a break but in all it’s decent . Can’t imagine me having one for a year even and it looking this good not to mention 60 yrs. Thanks s so much for looking and I hope you have a great day!
