One versus two pipe refers to how the piping is connected to your radiators, not how the condensate is returned within the basement or crawlspace. You can have a single pipe go directly to a radiator and the condensate come opposite the steam all the way but you need larger pipe and steeper pitches that probably aren't allowable in your long crawl space, so there you have a return pipe below the steam pipe. The return would go back in the bottom tappings (holes) with a Hartford Loop to keep the boiler from draining if there is a leak in the return below the safe water line. The equalizer drop from the steam piping to the hartford is to drop condensate out of the header so it is drier. Can you send directly a scan of the picture. I'll e-mail a sketch of what I think you had.
