Looking for some help on identifying which model of American Radiator I have in my house.

Thank you! Now I can calculate square footage of my radiators to see if my boiler is sized properly

Measure and compare but i think that is the right series.

Comparing by looks I also have Dan's radiator book looking through that those are definitely what I have.

Yes, it's a Corto. But there were a couple variations of the Corto. Measure the distance from the center of one section to the center of the next section. If it's 2-1/2", use the standard chart. If it's 3", use the Hospital Corto chart. But if it's 2", go here:

They are standard Corto. I was able to do my calculations and based upon the square footage and the output of my boiler it looks like the installer knew what he was doing when he sized it.
