The original roof vents on my 1953 18' Clipper can be opened from the front, rear, or both ends at once so the vent top goes straight up. There is an actuator mechanism at each end of the vent which controls this function, and each can be controlled separately. The knob indicates the actuators were
manufactured by Le Deau Mfg, Los Angeles, CA.

Three of my actuators are broken and I have only one knob. Does anyone know of a source for these old roof vents parts? for similar replacement parts? Has anyone found a fix for the old actuators that works? Any help or leads appreciated.
