Cast iron baseboard output

We have about 70' of this cast iron base board show in the picture. It is located in a house and we are trying to properly size a steam boiler to handle the load

I'm told that the cast iron element measures about 4" deep and is 6" wide. is has a sheet metal enclosure around it to enhance convection.

does anyone know a square foot EDR rating on this per lineal foot? Any idea who the manufacturer was on this?

    That is a convector and it sure needs cleaning to get any output.

    Look fo a manufacturer or name on it. If you can't find one measure them up and find a manufacturer that make one a similar size and use that rating. It will be close enough. Their is probably some information available on his site
