2" metal pipe into chimney in attic

Ive seen this before, but never really knew what it was for. 

1930s house, this went to above the floor behind the toilet. 1960s remodel and the pipe was just stuffed with a rag and plastered over. 

Went up and into the chimney. 

Was it a plumbing vent? Of some type of gas heater vent? In direct contact with wood, which makes me think it wasn't for any type of combustion vent.

    Neat. I'll go with plumbing. Or... at one time there were toilets (not the modern low flush kind!) which had a separate vent connection, just below the bowl rim, to remove ... ah... objectionable odours. We had a couple -- all now gone. Could have been that.

    All the plumbing appears to have been origional, galvanized and cast. And this went to the back of the toilet, so that would make sense. 

    This is a remodel job I'm working on. I should have taken pics before we demoed it. 

    I did use the pipe as a chase for my romex to other floors though. Just demoed the stuff in the attic into the chimney.

    Pipe was right next to origional cast vent. Then followed roof rafter to chimney from here.
