Hey gurus! Any information on these would be appreciated! Hoping for age, manufacturer, EDR. I’ve never seen these before. Found for sale on fb.

    Those would look great powder coated or some artwork brazed on. I would take one if they are reasonably priced, and ship able
    What is the dimension of those?

    The seller claims they are cast iron but it looks to be plate steel to me.

    Looks like steel with a steel tube wrapped around. Possibly no waterways inside the loop of tube?

    Would go great under a water bed.

    well someone else bought them so I guess this will remain a mystery

    Looks like venturi tee connections. That means water.

    EDR. get a tape measure and measure the length x the width x 2 (front and back)

    I wonder how that might work under my sleep number bed?

    After you make that expensive repair and you still have the same problem, What will you check next?

    Looking at the photo ,I don't know how old are those radiators are but being they are connected to a 1950's system. Someone found them for a deal .. They are butt ugly . How could you convince your wife ?

    There was an error rendering this rich post.

    Definitely hot water there is no provision for condensate.
    Those round dark spot look like a shadow of some internal structure.
    Looking at the edges I cannot tell if it is rolled steel seams or possibly an almost impossible casting. My money is on steel.

    Did these come out of a stable? They remind me of the multiple horizontal radiant pipe system that I see in some old stable buildings.
