On prewar transformers, maybe not specifically the type T, do not come apart easily. On many of the ones I have taken apart, the transformer is in the base and the speed control taps are on the top.  The wires from the transformer to the top make a U shaped harness so the top can be tipped up to allow limited access for a cord change.  But disconnected the top and bottom was not planed for.  On some of the later units I have found the interior potted in asphalt.  This is removable with a heat gun, but there is still an asphalt coating on everything.   It is possible to change a cord, but not much more. On the earlier units, with cast iron cases and slate tops, are assembled with threaded hardware and can be mostly dissembled. But the wire insulation is very brittle. Best not to do to much moving of the wires to keep the insulation from falling off. The copper wire is usually heavily corroded and soldering to it is difficult or impossible.
