    My guess would be it turns a 1 pipe steam only CI rad into a 2 pipe rad?? And vents the air also?
    Was it sawed off the rad spud?

    Looks like it was chopped off. I was thinking the same thing. But what would it have connected to at the bottom?
    Never stop learning.

    Steam in the top pipe, and condensate in the lower pipe.
    You could run smaller pipes and not the need the slope (headroom) for the counter flow piping.....maybe??

    Perhaps most of the rad air would be forced out the lower return.
    The vent on the side would maybe do what main vents do now.

    Looks like a Hoffman vent ... could it be a Hoffman #2 Vacuum Steam Vent on there?

    That’s kinda looks like Honeywell unique twin inlet fitting usually I have only seen on gravity hot water .thats pretty cool I would image some one used that maybe because they where unable to get to both side of the rad quite a neat trick for a what’s looks like 2 pipe air vent neato I ve made fitting similar to that for hot water system tying into cast rads using tees And a drip tube .they work good thanks for sharing peace and good luck clammy

    It was plugged so I didn’t get to see it in service but it has a brass internal piece is what caught my eye. Super neat dying to know original use was. Thanks for input

    There is nothing on it talking to home owner he said was installed in the 40’s and he inherited the house and says never been touched that he knows of minus removal of radiation from additions and renovations. Boiler was a snowman and was running as of this week!

    Perkins was half of Shaw-Perkins, who made the copper convectors you find in "E.D.R." starting on page 262. I'd bet that setup was for a long length of fin-tube to let you have the supply and return connections on the same end.
