Hi Les, There was a model of Heintzman, that had the tabs on a rail that moved with the centre pedal. On the end of the damper lever, there was a wire extention, with a flattened end that had thin felt glued to it. It would catch the levers, when the lever tray was raised. Check the ends of the damper levers, to see if someone has cut the extensions off I have seen them cut off and missing before.. Regards, John M. Ross Newton Hunt wrote: > I too am baffeled.
