Back when I was ten foot tall I ran a Holmes wrecker on a 48 Chev chassis and would like to know what model it was. I think I saw something one time that said "Traffic King" It had twin booms, the lattice type. It had the cradle and stiff legs with a large tool box behind the cab that opened by a cable inside the cab. The controls were on the back end and it had a slip clutch.I am just wanting to know what model it was. Incidentaly the first wrecker I ran was a Manly hand cranker on a 34 Chev. Thanks for any help.
