Here is an interesting one. Lakewood tow tabs were painted orange, similar to NMW. These two items were originally purchased in the early 1970's.
I wonder who copied who in the color department? Did NMW copy Lakewood with yellow, as Dave Miller alluded or did Lakwood copy NMW? Maybe they both did. I think Lakewood started using yellow as a signature color in 1970. I know earlier traction bars were black.
