Herman Nielsen Invisible Radiators ~1930
Does anyone know of any potential sources for parts for the radiators housing / vents. I have a house full of these radiators with broken damper gears / control knobs and some missing the entire radiator “face”.
Herman Nelson was merged into Amercan Air Filter some decades ago. These units have been out of production at least that long. You'd probably have to have something custom-made.
