Odd Radiator

If I could find my copy of EDR, I probably would not have to come to The Wall, but I need the answer in less time than it would take to buy a new copy -- or to find the oine I already own..  So ... does anybody recognize this beastie?  It is about 14 wide X 22 high and 3" thick.  If someone could send me the EDR rating, I would really appreciate it.

    never seen one quite like that!

    I can't come up with the manufacture's rating of that very unusual wall radiator, but I would assume that it is probably about the same as the American Peerless wall radiator of about the same dimensions.  

    Their Type 7A radiator measuares 13 5/16" x 21 7/8" x 2 7/8"   It had a surface area of 7 sq. ft.

    Information comes from American Peerless Wall Radiators, copyright 1920.

    Hope this helps.

    That's the H.B. Smith "X-Ray" wall radiator

    the rating for that one is 8 square feet. And yes, it appears in "E.D.R."
