I have a Proto 36" top box (I think) that's pretty old.
I bought it at a pawn shop for 20 bucks to stay at my unattended shop 1 mile away from my house.
Figured if anyone broke in, they wouldn't steal a beat up tool box.
Have a portable 1980's Craftsman box I got as a graduation present with the $79 tool set.
About 15 years ago (wow), I bought two 42" bottom boxes from a cragslist ad that listed about 50 "damaged in shipping" boxes for $100 each.
One is a Waterloo and I believe the other is branded Homak. They are identical to Craftsman boxes.
Price them now- YIKES.
One top box for that set came from a pawn shop and needs stripped and painted- Craftsman.
The other is a fairly recent floor display from Rural King.
I made a small tool box in 1983 industrial arts class.
Cut on a shear, bent on a brake, spot welded and soldered together.
Gave that to my wife a few years ago and she uses it.
