I have a radiator I can't identify. Seven small tubes, 12" wide, 38" tall. It's on a hot water system, originally gravity. I have three like this, various section counts.

It, and any other reference I've found, doesn't cover 7 tube radiators 38" tall. I can extrapolate, but I'm hoping someone has a better guess.MilanD said:This should be pretty accurate.

I realized after posting it doesn't have the height. Perhaps someone here has the EDR book.0

There's no name visible, but I think National was the only company that made a 38" tall, 7-tube radiator. Ratings are in Dan's "E.D.R.".All Steamed Up, Inc.

Thank you. There's a 1926 (year the house was built) national catalog available at archive.org https://archive.org/details/NationalBoilersAndRadiatorsCatalogNo.35_517 The style is called 'aero'.
That tells me 7 square feet a section, which was what I'd extrapolated from the tables I'd found. That seems oversized for the room it came out of, but we knew that.
All of my radiators are this style, in various widths, heights and lengths, except in one bedroom, which has a column type, and a basement one which is a more deco style (and a recent addition).
Catalog says lengths to 32 sections; I have a seven tube, 38 section, 20 inch high radiator in my living room. I wonder if it was specially ordered, or the builder put it together from two smaller ones.0
