I do not believe the cord is plug is original. I put a piece of rubber hose over the metal handle to make it easier to carry. I'm guessing that it might have had plastic on it originally but that's gone. It has two dials on the top. On the left is the fan speed control dial and it works great.
However there is an auto thermostat knob on the right side and the knob broke during disassembly. I have a replacement knob that is included that needs installed.
