Identify radiator type by this photo

Can anybody categorize the radiator in this photo? Cast iron column? Seems too skinny. Cast iron tube? Maybe, but I am guessing cast iron thin tube. House dates to 1935 and radiators are original. I have two other types and will post those pics separately. Thanks, y'all.

    Cast iron tube.

    Thanks, brother. Follow-up question. I seem to see conflicting info about measuring EDR. Do I measure radiator total width, or width of individual sections and then count the number of sections?

    Height from floor to top of Rad, number of tubes from front to back (looks like 4) and number of sections from side to side.

    Just count the number of sections and measure the height.

    4 tube cast Iron. measure the height. count the sections. the chart is EDR in Sq ft per section. Multiply. see the chart below

    So if your 4 tube radiator above is 26'' tall and 12 sections wide
    you have 2.75 sq ft EDR per section times 12 = 33 sq ft EDR for that radiator
