I am currently sizing a system now and can not find some of its current radiators in Dan Holohan's E.D.R. book in order to determine the water temperatures for this system. I have a few plain 4 tube radiators that have pipe plugs in them that say Logan on them. The sizes are as follows:

6" wide x 32" high x 29" long, 11 sections
6" wide x 32" high x 35" long, 14 sections
6" wide x 32" high x 38" long, 15 sections
7" wide x 26" high x 50" long, 20 sections

And a 5 tube, 9" wide x 36" high x 22" long, 9 sections

Also I have one radiator that is an ornamental radiator with a name of ##clow & sons Chicago on it. It is a three tube and measures 10" wide x 42" long and 16 sections. I missed the height when I was on the job site.

Does anyone have any information on these radiators or know their E.D.R.? Also what can I expect for them to hold in water capacity in order to size my expansion tank using John Siegenthaler's Hydronic Design Studio program?
