I have a 1933 1.5 ton truck that has a factory looking hole in the top rear of the cab for what I am told is a folding turn and stop signal. There were apparently operated via rope and pulleys inside the cab. By pulling the rope either a "turn" or "stop" arm would raise up or lower. My cab has the pulley hardware still intact, but the signals themselves are missing. Does anyone have any more information or possibly a pattern for this type of signal?
Thanks,
Greg
