Joan has “no idea” what this curiosity -found in the basement – is. Niilo knows what it is! But he’s keeping his memories and wisdom to himself.
Rob knew immediately, and could point out what happens at each point in the contraption: a steam trap, possibly from a train, possibly from some other application.
Per wiki: A steam trap is a device used to discharge condensate and non condensable gases with a negligible consumption or loss of live steam.
Do any of you readers recognize what application this particular steam trap belonged to?
