Weil McLain Cast Iron Baseboard radiators (6") - output?

I have a 1955-built house full of Weil McLain cast iron baseboard radiators - but not the standard number 9's that have plenty of info available on the web. These stand about 7" tall including the air gap below (cast iron unit is a around 6" itself).

Does anyone have the table of btu output per water temp associated with this size? Perhaps from an old manual or catalog? I can find the table for the number 9 radiators but not this smaller size. Thanks

    Weil-McLain low base:

    Look for 7" high old Burnham. The ratings are about the same. Close enough for hand grenades. I don't think they have made it for a very long time. Someone here will have the proper rating. But if they don't, the Burnham will be close enough.
