Interesting pictures and rack.
That is a cool looking rack, but I doubt if Jones and Laughlin (J&L) was the manufacture of that rack. They were into the making of iron and steel from ores and scrap in a big way. Is it possible that the name J&L was stamped onto the steel bars that made up the rack?
In other words, the steel came from J&L but was made into a tire rack by someone else?
