NMW out of New Jersey used to make a set of ladder bars in that configuration. At one time they did paint the bars yellow. The earlier bars were silver and then later burnt orange. The company now makes car dollies and that sort of thing. They advertise in the front of Hemmings in the color section every so often. NMW was a big traction bar company in the '60's and early '70's.
