Does anybody recognize this radiator?

Here is a radiator I have not seen before. There are 7 of these in a house that was built in 1932. You may not see it in the picture but there is a steam vent installed on the back of it- I don't know how the vent was installed unless they removed the radiator to do it. It's got an enclosure behind it and is recessed in the 2x4 wall. The cast iron front that you can see in the picture seems to be most of the radiating surface, but if you look in between the spaces in the front about 1/3rd of the way up is a cast section that's a few inches deep and high that looks a little like cast fin-tube. They're all about 22" high but the widths are different (17", 55",41",36"). I'm trying to determine if my boiler EDR matches the radiation. Does anyone know what the EDR of these are? Thanks for any help.
