    Appears to be a dual winding choke.

    Are you sure that both windings were not connected in series with the load acting as a choke?
    That would account for the same voltage if connecting it as a transformer.
    What was/is the original load?

    The apparent balanced windings and wire gauge/ No of turns still appears to be a Common mode choke to me.

    Could be why they were in a scrap yard?
    Also the same colour on in and out also appears to confirm the diagnosis.
    There would be many more turns for a mains Txfr.
